Fixes
elf/librtld.os: In function `process_envvars': : undefined reference to `__access'
...
when building glibc-2.3.x on cygwin
Idea from
http://sources.redhat.com/ml/bug-glibc/2002-01/msg00071/glibc-2.2-cygin-shared.patch
Basically, make glibc use .oST as suffix for 'object static'
instead of .oS, since cygwin has trouble distinguishing .os from .oS
(Original patch had .on, but .oST is more mnemonic for 'object static')
glibc-linuxthreads-2.3.5 also requires a patch, see
../glibc-linuxthreads-2.3.5/glibc-linuxthreads-2.3.5-cygwin.patch
[ forward ported to glibc-2.3.5 by Petr Cvachoucek:

Subject: Patches to build gcc 3.4.3 / glibc 2.3.5 on cygwin
Hi Dan,
following patches are needed to build gcc-3.4.3/glibc-2.3.5 toolchain
on cygwin. Tested to build toolchains for powerpc 604 and 750 targets.
