I would benchmark that, at least in the old days the results of PCH where
really mixed:

and only reliably gave an advantage on incremental builds. OTOH, generating the
PCH for a library was a singlethreaded bottleneck in the old build system and
isnt anymore in gbuild, when doing a toplevel make, so this might be mitigated.
Anyway, worth a benchmark IMHO.
