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:
