Well first off you want to find what 'cc' was invoked above.
See if it cored - if it is something that should have run successfully
on the host.

The fact that the errors say 'make:' rather than 'make[1]:'
indicates this is the initial instance, if it were a sub-make you could
add .META to the target that ran the sub-make and thus see from .meta
file which 'cc' was run.

You could perhaps write a trivial makefile (m) to do that.
Ie. give it something like:

.MAIN: all
all: it
it: .META
	${MAKE} -C ${.CURDIR} whatever

You *may* need

it: .META
	MAKELEVEL=0 ${MAKE} -C ${.CURDIR} whatever

to reproduce the cirsumstances better.
