Improving www/chromium build time on arm64

Hello all,

I'm running 13-STABLE on rpi4 8 and since firefox{-esr} is constantly tab
crashing and seg faulting I decided to give chromium a try.
chromium pkg isn't available for arm64 and I didn't found error log at so I decided to build it on poudriere.

It fails to build around 70% but my biggest concern is build time: 27 hours
for 70% compilation!

Just for comparison:
llvm15: 12h
rust: 9h
firefox: 6h

rip4 v1.5 8GB @ 2000Hz ~62 Celsius

Any hints on how to speed build? ccache?
Does cflags "-O -pipe" not present in compilation is related to build time?

Full log:


In file included from ../../base/check.h:11:

Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to
the maintainer.
