trivial diff: fix bug with EXTRA_MGNUCFLAGS and --use-subdirs

[Fergus Henderson]

Estimated hours taken: 0.25

scripts/Mmake.rules:
	For --use-subdirs, add `-I.' to ALL_MGNUCFLAGS rather than to
	MGNUCFLAGS.  This avoids problems where EXTRA_MGNUCFLAGS and
	MGNUCFLAGS_FOR_TARGET were being interpreted as gcc options
	rather than as mgnuc options, because `-I.' is a gcc option
	rather than an mgnuc option and so all options which follow
	it are assumed to be gcc options.
