glibc-2.1.3-cygwin.patch

linux下编译交叉工具链的工具源码

Fixes
elf/librtld.os: In function `process_envvars': : undefined reference to `__access'
...
when building glibc-2.1.3 on cygwin

Idea from
http://sources.redhat.com/ml/bug-glibc/2002-01/msg00071/glibc-2.2-cygin-shared.patch
backported to glibc-2.1.3.
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')
