[m-dev.] for review: LIBGRADES

[Zoltan Somogyi]

configure.in:
	Add options that allow the user to specify the set of library grades
	more precisely. Also add an option, --enable-minimum-grades,
	that reduces the installed grades to the minimum (asm_fast.gc,
	asm_fast.gc.debug.tr and hlc.gc), since this is useful to minimize
	installation time e.g. when installing a release of the day on a
	laptop.

Zoltan.
