+Subject: [PATCH] Fix endianess detection with musl-based toolchains
+
+Musl does not define __GLIBC__ and will not provide a __MUSL__ macro:
+http://wiki.musl-libc.org/wiki/FAQ#Q:_why_is_there_no_MUSL_macro_.3F
+
+This patch checks for the presence of endian.h and promotes the result
+to src/amd/Makefile.addrlib.am which executes the broken build command.
+Fixes compile errors detected by the autobuilder infrastructure of the
+buildroot project:
