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.

2012-09-26scripts: exporting (even empty) LIBRARY_PATH and/or LPATH breaks gcc

scripts: exporting (even empty) LIBRARY_PATH and/or LPATH breaks gcc

If either LIBRARY_PATH or LPATH is set, even to the empty string,
the gcc build breaks.

Fix that by bailing-out rather than re-setting.
