Subject: [PATCH] Fix e500 __fe_nomask_env use of __set_errno w/o CFLAGS-libm
Since the new _LIBC guard in 96c9a8f7d00cdf6bb7968a2390b9d87da8a45e2d we need
to use CFLAGS-libm (-DNOT_IN_libc -DIS_IN_libm) or we end up with linker
errors like:
lib/libm.a(fe_nomask.os): In function `__fe_nomask_env':
fe_nomask.c:(.text+0x26): undefined reference to `__libc_errno'
collect2: ld returned 1 exit status

Date: Mon, 5 Jul 2010 14:08:17 +0200
Subject: [PATCH] don't make __errno_location / __h_errno_location hidden
Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089)
__errno_location / __h_errno_location access has to go through the PLT
like malloc/free, so the linuxthread variants gets used instead when
compiling with -pthread.
