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

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.
