REALLY SLOW chromium compilation

Compiling www/chromium has never been a fast operation, but a couple of
months ago on my AMD Ryzen 5 2600X, it took a mere 16 to 18 hours to
compile, and the last couple of times it has been taking over two days!
I've been running 14.2-RELEASE since the end of January, and I believe
chromium started using llvm-19 to compile last December.  I can't think
of any other aspect of my system that changed more recently than that,
but I could be wrong.

Is anyone else encountering this as well?  Thanks!           -- George
