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
