RFA: support in src-release to create a release-style sim.tar.bz2

I checked the CVS modules that would be completely inside the
binutils+gdb git and it appears the sim module is the only usable
stand-alone one.

There are certainly "straddling" projects (having parts both inside
and outside binutils+gdb): insight and sid (not counting a historical
relic called old-gdb).  I'll leave those to interested parties as
straddling projects will have to solve that problem before they can
make use of any non-stand-alone sub-part tar-balls of a binutils+gdb
repository (like the existing naked-* CVS modules).  Sid may have to
be revived first.

The do-proto-toplevel change is needed to support files in
SUPPORT_FILES with paths like gdb/; the ln -s machinery
broke as you probably understand from the change.  Beware that DIRS in
SIM_SUPPORT_DIRS is a misnomer but not a new one; single toplevel
files (not just directories) have been included in it, way before
this change.

Tested by building a sim- out of a binutils+gdb
checkout using "make -f src-release sim.tar.bz2" and checking that the
difference to the "sim" CVS module was not unexpected compared to
e.g. the difference between a created binutils.tar.bz2 and the
"binutils" CVS module.

N.B. this requires a patch to align sim/common/ with
gdb/common/, posted to gdb-patches@.  I expect to
commit that patch before this one.

Ok to commit?

	* src-release (do-proto-toplevel): Support subdir-path-prefixed
	files in SUPPORT_FILES.
	(SIM_SUPPORT_DIRS): New variable.
	(sim.tar.bz2): New rule.
