community/dynamips: fix byte order detection
Use the generic gcc/clang/suncc __BYTE_ORDER__ macro to detect platform
byte order instead of hard-coded architecture detection which is wrong
for ppc64le (always assumes POWER is big-endian) and lacks any knowledge
of mips*.
This change covers s390x too so remove s390x-support.patch.
