This one is already fixed in uClibc commit 
5f1678b1df1153277590b114ccafcf6171923d75 in a different form, that's the 
reason the patch applies but it does nothing new.
It can't fix anything related to any target different than powerpc 
e500.
Regards.

This one shouldn't be required either since it's just a build fix for 
SPARC which was fixed in another way most likely by uClibc committ
96c9a8f7d00cdf6bb7968a2390b9d87da8a45e2d
Regards.

+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

+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
