[crosstool-ng] patch for glibc-2.3.6

Hello,

I still need an old glibc-2.3.6, so i patched it for make it working for ppc 405 softfloat.
Here are the patches.

Note:
patches are in dir glibc/2.3.6 except 310-linuxthreads... which should be put in glibc/linuxthread-2.3.6

Regards,

Julien 
GCC trunk now has multiple internal headers directories, one
containing the self-contained GCC-provided headers and one containing
the <limits.h> (not self-contained but including libc's <limits.h> or
a fixed version thereof) and the fixed headers; more such directories
may be added in future.

When glibc uses -nostdinc, it needs to use -isystem options for all
these internal directories.  This patch teaches it about the
include-fixed directory (and is harmless with old GCC versions without
that directory).

2007-03-18  Joseph Myers  <joseph@codesourcery.com>

	* configure.in: Also pass -isystem option for GCC's include-fixed
	directory.
	* configure: Regenerate.
