Introduce quiet build

Browse Source 
Make forthstrap quiet by default. Use generic rules when possible, unify
the rules and cleanup white space. Use ld flag --whole-archive to avoid
some local rule use. We can also remove some hacks introduced to avoid
missing symbols.

Fix problems brought in by ld flag --whole-archive:
 * x86: fix missing nvram symbols
 * PPC: disable misc.S build for qemu (conflicts with our libgcc)
