I'm not 100% sure I understand -- by "solution" here, you mean
COMPILE_FIRST?

Because it's slower to do eln compilation in COMPILE_FIRST -- it's
faster later, once Emacs has been built with nativecomp. So these extra
eln bits should be done around the same time as compile-main, or rather:
During compile-main, so that we get max parallelism, too.
