scripts: move backtrace marker to CT_WORK_DIR

Avoid error when commands in scripts/crosstool-NG.sh fail
before CT_BUILD_DIR is set.

So we need to remove the backtrace marker of a potential previous
build. Previously, it was implicitly removed because we did remove
the directory it was in, which is no longer the case.

The m68k mcpu processor does not like unaligned access

Disable at least mcpu32, m68010 and m68020. These processors certainly

do not like unaligned accesses.
