We need to pass an argument to ld for setting the endianness when building it for MIPS architecture, otherwise the default one will always be used (which is big endian) and the compilation for little endian will always fail showing an error like this one: LD foo.o mips-linux-gnu-ld: foo.o: compiled for a little endian system and target is big endian Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Reviewed-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
