Subject: take byte order from gcc if gcc has defined it
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=a3b20f67b35e26813d02e08043db2a5d9263f255

take byte order from gcc if gcc has defined it

this only works with gcc 4.6 and later, but it allows us to support
non-default endianness on archs like arm, mips, ppc, etc. that can do
both without having separate header sets for both variants, and it
saves one #include even on fixed-endianness archs like x86.
