If you have code like this:
#include "header.h"
and you want it to include 'another_directory/header.hh' instead, then
use a flag to instruct the compiler to look for headers in the other
directory first, and change the file suffixes there from '.hh' to '.h'.
You'd wind up with
big_endian/header.h
little_endian/header.h
and then for example with gcc you could set CFLAGS='-I big_endian'
or '-I little_endian'.
If the makefile needs a list of headers for some other purpose, use
something like:
$(wildcard $(endianness)/*.h)
with a suitable value of $(endianness).
