kernel/linux: change m68k/no-mmu linux arch tuple to use -uclinux

GCC requires m68k arch tuples to be *-*-uclinux-* to support Linux on
no-mmu m68k (ColdFire) cpus.

Blackfin arch tuple must be *-*-linux-uclibc for FD_PIC_ELF toolchains,
so we cannot just switch to uclinux for no-mmu Linux toolchains.

Set the default behavior on alpha to use -mieee since the large majority of
thomas@1461
     6
time we want this (bad/weird things can happen with packages built without
thomas@1461
     7
-mieee).

To satisfy those people who may not want -mieee forced on them all the time,
thomas@1461
    10
we also provide -mno-ieee.
