uClibc: port linuxthreads errno patch to 0.9.33.2
Without this patch programs using libglib2 (libsoup, etc.. ) and pthread may be broken. Signed-off-by: Sagaert Johan <sagaert.johan@skynet.be> 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
