Add an option to eglibc to optimize for size using -Os.
Signed-off-by: Richard Strand <richard.strand@icomera.com>

We can not rely on the user-provided version string (be it via the
choice, or manually entered), so fallback to reading version.h,
which is both reliable and always present.
|
|
- 'nochdir' must be the first option
- have systematic pushd/popd, even if nochdir

It's now been a while that glibc switched to git from cvs.
Get rid of cvs to download glibc; this will make for a good
cleanup before we add git support! :-)

Since we merged the 32/64-bit archs, and we explicitly used
the Linux kernel arch name, we can get rid of CT_KERNEL_ARCH.

If the selected ARCH is dual-bitness (eg. supports 32- and 64-bit),
then we need to know the correct place where to fetch some headers.
Currently, this applies only to x86 variants: i386 and x86_64.
|
|
Using this: tar cf - -C "/some/place" |tar xf - -C "/some/other/place"
to copy a directory to another place does not properly fail (when it does).
Using this instead: cp -av "/some/place" "/some/other/place"
makes it easy to see why and how it failed.
Impacted:
libc/uClibc
debug/ltrace
tools/sstrip
scripts/populate

At the headers install pass, there's no compiler to test for the size
of long double. Help it: we know that the compiler does support 128-bit
long double, in the IBM extended precision.
Kindly pointed out, and explained, by Mike FRYSINGER:

The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
So, allow user to use a CVS snapshot to benefit early from fixes
and enhancements to newlib.

build step:
- ./configure
- remove glibc-specific options
- pass the target CFLAGS in the correct variable
- make:
- build in //
finish step:
- print proper message in finish step
|

newlib handles the build/host/target a bit differently as one would expect:
build : not used
host : the nachine that builds newlib
target : the machine on which newlib will run

glibc snapshots have not been updated for about the
past 5 months. Consider them to be deprecated, now.

Build eglibc with -O2 as a fix/workaround to building
seemingly-native toolchains (see docs/overview.txt).

The option to retrieve snapshots is already handled by
the generic 'specific date' and 'use latest' entries.
No need for a special case, as there's no code for it.

Fix the test to check if download is forced.

|
During the conversion to using bash arrays, the glibc build script
was improperly converted, and contains an incorrect variable
assignment to the config_options array.
|
|
For every components where it makes sense, use bash arrays (instead
of a string with space-separated values) to store the options pased
to ./configure.
|
|
Change extra_config from a string to a array of options.

|
|
Rewrite part of the code to better match the rest.
Most notably, rewrite handling of:
if [ ... ] && [ ... ]
to:
if [ ... -a ... ]
This has the positive side effect of calling "[" only once, although
"[" is probably a shell built-in.
|
|
To test for existing files, use "[ -f blabla ]", not "[ -a blabla ]"
Checking for a file exsitence with "-a" is a bashism.
Althoug we _are_ using bash, it's disturbing as it can be misread as
the 'and' operator. Fix by using "-f".

- introduce the config dir, where components can store their config files
- move the munged uClibc config file to the config dir
- now, the state dir really is an indication that a build can be restarted
Thanks to Groleo Marius <groleo@gmail.com> for spotting the inconsistency
of the state dir usage, and suggesting this change.

- recently, tarballs for glibc 2.8 and 2.9 have appeared on the GNU ftp site
- always use a dot in version strings (eg. 2.9, not 2_9)
