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.

     5     Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGS

     6     

     7     UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags

     8     and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation

     9     flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is

    10     specified at last. So we need to change the order of these option flags
