   4 Subject: [PATCH 1/1] Fix endianess detection with musl-based toolchains
   5
   6 Musl does not define __GLIBC__ and will not provide a __MUSL__ macro:
   7 http://wiki.musl-libc.org/wiki/FAQ#Q:_why_is_there_no_MUSL_macro_.3F
   8
   9 This patch checks for the presence of endian.h and promotes the result
  10 to src/amd/Makefile.addrlib.am which executes the broken build command.
  11 Fixes compile errors detected by the autobuilder infrastructure of the
  12 buildroot project:
