uClibc: add linuxthreads/errno fix for 0.9.31 / 0.9.32-rc3
See uclibc #2089 for details. This is still not included upstream, but lets include it anyway as several people have been running into the issue. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

+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
