Subject: [PATCH 1/1] 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:
http://autobuild.buildroot.net/results/e27/e27a9a95f72dba3076549beb2a2ccfdbea2fcfee/
