PR modula2/111756: Re-building all-gcc after source changes fails to link

When having modula-2 enabled in a development tree and there are any
changes that trigger rebuilds in m2/ doing a 'make all-gcc' in the
build directory might fail due to lack of dependency tracking.  This
patch introduces build dependencies into gcc/m2/Make-lang.in using -M*
options.  The patch also introduces all -M* options to cc1gm2 and gm2.
