Re: pc-bios/optionrom: when/why do we build it?

[Michael Tokarev]

Maybe a more general question would be:
what is our main build entry point?  Is it `make` (or `make all`)
still, or is it meson now?

For this specific optionrom thing, I'd say we should add a separate
rule to the top-level Makefile (or to meson.build) which is not
run by default but can be run explicitly, like `make optionrom` -
this will check if pc-bios/optionrom/config.mak is there and either
run make in this subdir or complain saying no i386 compiler is found.

Thanks,
