I recently noticed that libphobos isn't enable by default on 32-bit
Darwin with the target triples determined by config.guess. E.g. on a
Darwin 15 system the target triple is something like
i386-apple-darwin15.6.0 while configure.tgt only matches
i?86-*-darwin1[2-7].
This patch also allows such minor and micro versions.
Tested on i386-apple-darwin15.6.0.
I'd commit this as obvious, but there's more: on older Darwin versions
(9, 10, and 11), configure.tgt only sets LIBDRUNTIME_ONLY. However,
toplevel configure.ac doesn't take this into account when deciding
whether to enable libphobos or not. I wonder if it should, though. I
guess it could: on my Darwin 11 system, test results (with explicit
--enable-libphobos) aren't too bad:
