wishlist for GNU compilers (Best way to have a port...)

This is not an answer to your question, but a related comment...

What I always wanted from the various GNU compiler-ports (be they
C, Pascal, Fortran, etc.), is for all of the possible architectures
to be options:

	OPTIONS+=	MIPS	"Enable MIPS arch"	on
	OPTIONS+=	FOO	"Enable FOO (beta)"	off

This would be similar to how the ghostscript ports are build --
each printer driver is an option, most of them are ON by default.

The options for each GNU-compiler would start from the subset enabled
for binutils (a separate port, LIB_DEPENDed on by the ports of
compilers and debuggers). The binutilis port would, by default,
support ALL architectures known to upstream developers. Eventually,
the main system binutils will be built that way too, but it is best
to practice on the ports, of course :-)

This would allow any FreeBSD machine to generate code for any
architecture (being able to /run/ that code has nothing to do with
the ability to /generate/ it!), and analyze any core-dump.

Ideally, each architecture back-end would be a port of its own --
like Apache "mods", for example -- but, without upstream support,
this is way too much hacking...
