i don't think we should bother trying to make asan work on
sun2.  will need some minor makefile/sets updates to make it
possible to not build sanitizers at all, and it needs a name
as we already have MKSANITIZER, which turns on _linking the
build with a sanitzer_, so i was thinking MKGCCSANITIZER
would turn off building the GCC sanitizer libraries.

(there _could_ be a use-case for building apps cross for
running on the host, but someone else can do that ;)

thanks.

ps: it's possible your patch is good and fixes a bug in the
existing options -fno-jump-tables / -mlong-jump-table-offsets
that seem to work for m68k building sanitizers, but should
be gated upon _those options_?  maybe ask upstream ;)
