No it doesn't:

  LD      core/built-in.o
/home/peko/source/buildroot/output-sw/host/bin/mips-img-linux-gnu-ld: core/swupdate.o: compiled for a little endian system and target is big endian

scripts/Makefile.build:224: recipe for target 'core/built-in.o' failed
make[3]: *** [core/built-in.o] Error 1
Makefile:480: recipe for target 'core' failed
make[2]: *** [core] Error 2

With this defconfig:

I will change it to explicitly pass CC="$(TARGET_CC)" LD="$(TARGET_CC)"

Bye, Peter Korsgaard
