Re: [toplevel] Overhaul detection of target compilers

This patch makes the search for target tools simpler, more orthogonal
and less brittle.  It is necessary to enable parallel processing of
multiple directories in toplevel bootstrap: I agreed with Alexandre
Oliva that it is better to fix this issue, so that --enable-bootstrap
need not disable parallel processing of the toplevel Makefile.  Then we
can fix PR/22340 (the remaining severe bug in toplevel bootstrap) in the
proper way.

I think I can approve it for GCC, though you should hold off a few days for (a) build-system maintainers to comment, and (b) src/ approval.


In any case, I think this is a terrific cleanup.
