main.mk: target refactoring

Browse Source 
The issue with the original hasty code that stuck around
was that it bluntly ignored any ifdef/ifeq constructs due to
an obvious reason of being essentially a grep, not a makefile
interpreter.

It's now fixed so that e.g. arch-specific targets won't pop up
for no good reason.

Thanks ldv@ for discussion and a reminder about the dump mode
(make -p).
