games-util/libstrangle: enable abi_x86_32 by default

Similarly to what's done for wine and friends, unsure why haven't done
this in the first place considering this has no further multilib deps
(this doesn't link with any libraries in DEPEND, what this uses will
depend on what applicates/games are linked with themselves).

Remove warning too, assume anyone manually turning it off would know
what they're getting into.
