what about setting DISTRO_LFLAGS to -m32 ?
I added in targets/buildtarget the following lines but it did not work :(
EXTRA_CFLAGS=-m32 EXTRA_LFLAGS=-m32
However I tried to build coreboot with buildrom on the same machine and it worked fine. Where do I have to look to understand how buildrom configures coreboot before building it?
