Revert "uClibc: port linuxthreads errno patch to 0.9.33.2"

Browse Source 
This reverts commit 1d8c3e6caf

The forward port breaks compilation at least for SPARC NPTL toolchains:

LD libuClibc-0.9.33.2.so
libc/libc_so.a(pipe.os): In function `__GI_pipe':
(.text+0x38): undefined reference to `__GI___errno_location'
collect2: ld returned 1 exit status

Easily triggered by a "make qemu_sparc_ss10_defconfig && make".

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.
Based on http://github.com/mat-c/uClibc/commit/328d392c54aa5dc2b8e7f398a419087de497de2b
