Confirmed.

You'll find that some of these already have the proper settings.  That's
great.

You'll also find that you can't add FAST_FORMATS_OMP checks to LM,
because its use of OpenMP is in code shared with other formats.  That's
life.  You'll have to skip adding FAST_FORMATS_OMP checks for LM.
I hope it's the only format like that (besides the dynamic formats,
where we already made the opposite decision).
