firefox-73.0 build fails under -current

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

With fully updated pkgsrc tree and several pkg_rolling-replace runs,
firefox-73.0 fails build for me under
# cat /kern/version
NetBSD 9.99.47 (GENERIC) #8: Tue Feb 18 14:06:06 GMT 2020
        sysbuild@ymir:/home/sysbuild/amd64/obj/home/sysbuild/src/sys/arch/amd64/compile/GENERIC
....

It is not that long log file, it happens fairly early in the build
process. The first error messages are:
...

many more like this and eventually

and at the end rust panics:

....

rust 1.41.0 built ok.

Not knowing anything of substance about C++, perhaps some standard
definition missing? Prior to this error there was a message regarding
the building of virtuanenv - the python2.7 one fails, it then
continues with python3, which succeeeds but with two optional
environment package failed.

Previous versions of firefox have always built for me, at least for a
year; not to mention that they actually work well.
