[Gm2] gcc-5.2.0 and gm2

[Gaius Mulley]

Hello,

gm2 now builds cleanly when grafted onto gcc-5.2.0.  I've seen it build
on both aarch64 and x86_64, both run regression tests and report similar
errors.  Here is the result of the aarch64 on the odroid (Ubuntu 16.04):

I'm in the process of double checking the tarball on floppsie.  I plan
to attack the gcc/gm2/Make-lang.in to reduce build times and remove the
multiple rebuilding of the parser source files.

Preliminary tests on a x86_64 platform show that some of the tools (gm2m
doesn't work and I think the preprocessor invocation is failing).  But
the compiler behaves (cc1gm2 and gm2) well, I've built the physics
engine and maze generator and both behave as expected
