4Subject: [PATCH 5/7] build: unify and fix endian tests
5
6Unify the endian tests out of lib/ccan/wscript into wafsamba since
7they're almost cross-compile friendly.
8While at it fix them to be so by moving the preprocessor directives out
9of main scope since that will fail.
10And keep the WORDS_BIGENDIAN, HAVE_LITTLE_ENDIAN and HAVE_BIG_ENDIAN
11defines separate because of different codebases.
