build.sh: fails at step "link clang/clang"

[N]

It appears that the web report form of gnats is having problems at
the moment, and report-pr(1) needs more pasting:


on am64 8.1 release with gcc, while trying to upgrade to current with clang:
I'm attempting to go from 8.1 release gcc to current with clang:

With a cvs checkout from yesterday (and also 2 days before yesterday) it fails 
at:

You can check with dmesg, but this usually means that the system ran out of
virtual memory. You can try to increase swap space
clang is known to need *lots* of ram

Oh. Doh. This makes sense. It's a bhyve with enough CPUs, but the 4096 MB RAM 
wasn't
enough then.

Thanks!

It's not clang, it is ld. It's ~540MB peak RSS here for a non-debug
build. Debug builds are much worse though.
