Add a "make strip" target, to make doing the official build easier.
We want the official build to have stripped binaries for size reasons,
so do it right and make it an actual build target.

Remove -s for host binaries; current practice is to let the distro
packaging systems do that themselves.  For the official binaries, we
should probably strip them, but via an external tool.

Move the MCONFIG files into a mk/ directory and give them more
descriptive names.

This is purely a cosmetic change to make the 'include' directives a
bit more coherent by making it obvious exactly which MCONFIG file
we're including. For example, in com32/lua/src/Makefile we exchange
the line,

	include ../../MCONFIG

for the much more comprehensible,

	include $(MAKEDIR)/com32.mk

Fix a couple of _FORTIFY_SOURCE failures which are nuisance warnings,
but fortunately not too hard to just plain avoid.

We need to include the size of the ADV in the range of data that needs
to be mapped.
