Perhaps a better idea would be to add a 'tools' or 'bootstrap' target
to the build system.  The new target would build and install all of
the utilities usually used by the build system, e.g. gcc, gas, ld, nm,
tsort, flex, yacc, &c.  It could also do so in a way that minimizes
the number of tools used in the process, e.g. it could use flex's
initscan.c instead of scan.l.  If we really want to get cute we could
even rearrange the order such that the whole process only needs a
minimal set of tools (gcc, gas, ld) at the start.  Thoughts?
