+Subject: [PATCH] host/xtest: Adjust order of including compiler.h
+
+compiler.h defines some defines which violate libc namespace e.g.
+__unused, this works ok with glibc but fails in awkward ways with musl
+the reason is musl uses __unused in its internal structures and this
+define in compiler.h conflicts with system headers causing errors like
+
+recipe-sysroot/usr/include/bits/stat.h:17:19: error: expected identifier or '(' before '[' token unsigned __unused[2];
+                   ^
+including compiler.h afer sys/stat.h fixes the problem.
