[Gc] fix boehm-gc on Debian/m68k

Hi,

there’s no getcontext(2) on Debian/m68k but boehm-gc tries to
use it (and fails). This causes an FTBFS in w3m, but using the
gctest.c programme from gcc 3.4.6 is enough to expose the bug.

root at ara2:~ # gcc gctest.c -lgc
root at ara2:~ # ./a.out
Getcontext failed: Use another register retrieval method?
Aborted

I’ve attached a diff against your CVS which _should_ fix the
problem (not tested), and currently am preparing one against
the Debian package (7.1 still) which will be tested (with the
same effect, just a different location for the ifndef).

Please review and, unless buggy, apply.

Thanks,

FWIW, I'm quite impressed with mksh interactively. I thought it was much
*much* more bare bones. But it turns out it beats the living hell out of
ksh93 in that respect. I'd even consider it for my daily use if I hadn't
wasted half my life on my zsh setup. :-) -- Frank Terbeck in #!/bin/mksh
