Can you reproduce this just building a LINT kernel?  I cannot, and
I fail to see how this could be a problem.  The failed "cc" command
is run from ${.CURDIR}/../../../${MACHINE_ARCH}/acpica/Makefile and
it only runs after assym.s was created.  But I have found a problem
building assym.s manually which needs fixed kmod.mk:

If you can reproduce the breakage, please put the complete
combined stdout+stderr output from a failed i386 LINT build
available somewhere for download.
