Is there a technical problem blocking this?

If we used configure.tgt and:
	switch "$target"
	 *-*-linux* ) "objs=objs symfile-mem.c"
then all GNU/Linux systems will always and consistently include 
symtab-mem.c.  We don't, they don't ...

We've already got configure.tgt checking OSABI and configure.host 
checking FLOATFORMAT so there's plenty of prior art.  Further, 
modifying/merging just that file is going to be a lot easier than 
modifying/merging all the individual *.mh files.
