Yes, and the magic is slightly hidden:
# XXX stuff looks for "../config.m4"
dummy:
mkdir dummy
${.OBJDIR}/config.m4: ${.CURDIR}/arch/${GMP_MACHINE_ARCH}/config.m4
rm -f ${.OBJDIR}/config.m4 && cp ${.CURDIR}/arch/${GMP_MACHINE_ARCH}/co$
CLEANFILES+= config.m4
in external/lgpl3/gmp/lib/libgmp/Makefile.
So the arch/.../config.m4 file is copied to ${.OBJDIR}/config.m4 and should
be found from there.
