branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

(Partially) apply upstream patch 1334869bf0ea668e58e1c72daa3c09c1a95b5d81
to properly protect code-paths depending on execinfo.h (for backtrace(3)).

+    [PR-172] Fix compilatioin issues on OpenWRT
+    
+    Fix SHA1_* function names
+    Fix unused variables and functions

+"Yann E. MORIN" <yann.morin.1998 at free.fr>:
+    For buildroot, I removed the SHA_* fixes, as we're not affected.
+    No point in fixing something that does not bug us.
