After this series, if we are building on a target unknown to u_endian.h, 
so it can't determine the endianess, sha1.c now builds for big-endian.

This choice is made silently, but fortunately mesa-sha1_test fails when 
built for the wrong endianess, so there is some hope to notice this...

Subject: [PATCH] Also include endian.h on cygwin

If u_endian.h can't determine the endianess, the default behaviour in sha1.c
is to build for big-endian
