The file sha1dc/sha1.c requires big endian to be defined by the compiler. If it is not defined, then it defaults to little endian mode, which when compiled and ran on a big endian machine results in a sha1 mismatch.
This change will allow git to correctly detect big endian on GCC 4.2 and GCC 4.0 running on PowerPC Mac OS X 10.4 and Mac OS X 10.5, resulting in a successful build that works correctly.

fix gcc 4.0 big endian sha1
Currently, sha1.c is compiled in little endian mode when using gcc 4.0
on Mac OS X 10.4 PowerPC (which is big endian). This results in a build
that always states there is a sha1 mismatch. The below patch allows big
endian to be detected correctly using GCC 4.0 and probably older
versions as well.
