These test files are currently "intended for use on x86 hosts", but most
of the tests using them can still pass when cross-compiled to x86 on an
arm64 host.
This patch enables non-x86 hosts to run the tests by specifying a
cross-compiler via CROSS_COMPILE. The list of variables it sets is taken
from the top-level Makefile. It would be possible to automatically set
an x86 cross-compiler with a few blocks like:
ifneq ($(shell i386-linux-gnu-gcc --version 2> /dev/null),)
CROSS_COMPILE = i386-linux-gnu-
endif
But it wouldn't propagate to the binman process calling this Makefile,
so it's better just raise an error and expect 'binman test' to be run
with a correct CROSS_COMPILE.
