No objections here. I see it as adding slightly more risk to this patch's
potential impact on Windows builds, but if Git-for-Windows is okay with that,
I'll go ahead and fold RUNTIME_PREFIX_PERL into RUNTIME_PREFIX for
simplicity's sake.

I'll add a "NO_RUNTIME_PREFIX_PERL" flag as per avarab@'s suggestion as a
potential mitigation if a problem does end up arising in Windows builds,
with a note that NO_RUNTIME_PREFIX_PERL can be deleted if everything seems
to be working. What do you think?

Great news, thanks for doing this!
