kernel/linux: add alternate download locations

Since kernel.org is dead, and there is no announced or known estimated
time or return to normality, it is impossible to download any kernel at
this time.

Add a known-working mirror.

cc/gcc: speed up the build a little bit

Even if the current process is highly parallel, crosstool-NG spends most
of its time in single-job steps on fast machines (with a 12-CPU system,
I approximate the parallel vs. non-parallel time to be in the order os
1 to 3; that is crostool-NG spends two-thirds of its time running
non-parallel jobs).

Some steps to build gcc can be paralleled, gaining a litle bit of time
on the whole compilation.

cc/gcc: libgcc_eh.a may be required, even from the stage-1 compiler

Building uClibc with libubacktrace requires libgcc_eh.a to be available,
but gcc does not build it unless it is configured to generate shared libs.

However, libgcc_eh.a does not *require* shared libs support, as it is a
static library.

libc/uClibc: add patch to fix fork in threads with ARM EABI

uClibc-0.9.32 requires libgcc_eh.a (for ARM EABI), but only when libubacktrace
is enabled. As this is not the default, provide a workaround to disable linking
with libgcc_eh.a if libubacktrace is not selected.

This will however still break if uClibc is configured to enable libubacktrace,
but it requires a fix in gcc, and we can take care of that later.

binutils/binutils: fixup version strings

Recently, all binutils versions have been renamed after a GPL compliance
issue was found and fixed in binutils;
http://sourceware.org/ml/binutils/2011-08/msg00198.html

Although legacy symlinks have been put in place, we should now use
the new, real version strings.

Old versions are no-longer available since the rename (eg. 2.19 has been
superseeded by 2.19.1, and only 2.19.1a was regenerated).

In case both are installed, both are used. This means that it

scripts: fix sysroot prefix dir

The sysroot prefix dir was broken in #4960f5d9f829 due to a mishap
when making the out-of-sysroot lib/ symlink: the './' was mistakenly
changed into a single '.' .

Although Jonathan suggested restoring the missing '/' to restore it to
normal operation, I prefered using an explicit pushd/popd to be extra
sure of the symlink location and target, along with a fix in the sysroot
relative directory calculation.
