complibs/ppl: backout #9f0de857cb05

The patch breaks the build on most machines,
while the purpose of the patch is dubious.
So, simply back it out.

debug/gdb: properly remove build tic

tic is isntalled in buildtools, not in the toolchain's bin dir.
Plus, it may have an extension...

debug/gdb: Fix compilation for Mingw hosts

GDB requires PDcurses instead of ncurses while running on Windows.
So, do not always compile ncurses in case GDB needs to build.

PDcurses is provided by an earlier build step and is not described in
this file.

cc/gcc: baremetal requires a two-pass process

Here, we implement a highly ugly hack. I'm not proud of that one...

To build the libstdc++ library, the compiler requires the C library. In
case we build for non-baremetal, this is normally handled by the final
step, later.

But in the case of bare-metal, we never go through the final step (because
it does not work, and it seems complex enough to make it work), so the
baremetal compilers are issued out of the core step.

libc/newlib: build in the 'start files' pass

A few facts:
- building the C library requires a proper core compiler
- core compiler is issued from one of the core passes
- the C library is required to build libstdc++
- newlib is only built for baremetal
- in bare metal, the final compiler is issued from one of the core passes

So we need to build the C library between core pass 1 and core pass 2.
The only place is eithe libc_headers() or libc_start_files(). The most
pertinent seems to be libc_start_files().

So we build newlib from libc_start_files(), and leave libc() empty.

cc/gcc: store core build rules in an array

libc/uClibc: apply the threading model to the configuration

The threading model shall be be set in the .config file.
Also, offer the choice between 'old/stable' and 'new' linuxthreads.

config: add support for a second part of the generated choices

Some components have configuration options that can depend on
generic options, so they should go below those.

uClibc for example:
- has its own options (wchar...)
- uses the generic options (threads...)
- if linuxthreads chosen, offers two impls

So we need to be able to split the components options in 2,
one part that is above the generic options, and one part that
ends up below the generic options.

scripts/wrapper.c: Under MacOS set DYLD_LIBRARY_PATH

docs/overview.txt: Provide short mercurial HOWTO

The usage of hg mq is imho not very well documented.
Give a short intro for the most important use cases
for contributions to ct-ng.

yann.morin.1998@anciens.enib.fr:
Slightly rewrote the explanations for the introductory message.

ct-ng: Add ability to configure and use some GNU tools

Make the paths to libtool, objcopy, objdump, readelf, patch configurable.

scripts/build/internals.sh: Always use binary wrapper under BSD/MacOS

The shell wrapper script uses a nonportable call to readlink.
Thus, always use the binary wrapper under BSD/MacOS.

yann.morin.1998@anciens.enib.fr:
Use 'case' instead of 'if'.

scripts/wrapper.in: Add a comment about readlink not being portable.

Documented that the call to readlink will not work on BSD systems.

configure: make call to readlink portable to non-GNU (BSD) systems

The argument '-e' for readlink is a GNU extension.
In setting the variable 'where' the argument '-e' is not necessary, thus eliminated.

scripts/crosstool-NG.sh.in: On MacOS/BSD use the output of CT_DoConfigGuess for CT_BUILD.

On 64bit MacOS `gcc -dumpmachine` gives i686 for the host machine.
This conflicts with the expectations of some following configure scripts
that a 64bit x86 is given as x86_64; i686 is understood as a 32 bit machine.
config.guess sets the host machine in CT_BUILD correctly.

yann.morin.1998@anciens.enib.fr:
As suggested by Khem RAJ on the ML, always use config.guess.

configure: Do not require stat to be of GNU coreutils

calls to stat have been made portable, thus it is not necessary
that the GNU version is present on the user's system.

scripts/functions: Use stat correctly on non-GNU (BSD/Darwin) systems.

Call to get the directory mode depending on $CT_SYS_OS

yann.morin.1998@anciens.enib.fr:
CT_SYS_OS has changed on Linuxsystem, it only gets the kernel name "Linux",
and not the system name, 'GNU/'.

build/internals.sh: Replace nonportable call to stat

The call to stat to find out if a file is a symlink works only on GNU systems,
and the replacing portable call to readlink is also shorter and more concise code.

yann.morin.1998@anciens.enib.fr:
Apply simpler test, after discussion with author and Arnaud LACOMBE on the ML.

crosstool-NG.sh: suppress failure message from uname -o

On non-GNU systems (BSD/MacOS) there is no uname -o.
Suppress the failure message on these systems in the
call to set CT_SYS_OS (uname -s actually sets this variable).

yann.morin.1998@anciens.enib.fr: remove 'uname -o' altogether.

cc/gcc: use proper host compiler for canadian bare-metal

While compiling a canadian toolchain for host=mingw32, build=linux,
