Looking more closely, I'm pretty sure this is the compiler bug
described in tools/test-gcc.sh:
# Also, on several compilers, -combine fails if code is emitted with a
# reference to an extern variable that is later found to be externally
# visible - the compiler does not mark those variables as global.
# This is being worked around by ordering the compile objects to avoid
# this case.
as such, I think the patch below should fix it.
After the release, I think SeaBIOS should just drop support for
"-combine" - gcc 4.6 no longer supports it and -flto is the preferred
