systemd: fix endian detection for powerpc

Fixes http://autobuild.buildroot.net/results/d53/d5305af6e47da7a577e391c96328ca952c149cd1/

Apply two patches from upstream git to fix powerpc endian detection. These patches
are already part of systemd v216, so they should be dropped when the package
is bumped.

+Subject: [PATCH] always check for __BYTE_ORDER == __BIG_ENDIAN when checking
+ for endianess
+
+Let's always stick to glibc's way to determine byte order, and not mix
+autoconf-specific checks with gcc checks.
