Also fix the run by setting up the environment in non-deprecated way.
Always run with --debug to understand better what sort of stuff is happening in
the background. Also split out the bmake bootstrap stage (takes about 31s on
ubuntu, but 1m14 on macOS?)
Drops the dependency on coreutils (realpath, nproc) and thus (?) fixes macOS to
be just as fast (4 logical cores vs 2 physical cores before, go figure.)

The Ubuntu /bin/sh (dash) removes all environment variables that contain
characters outside the [a-zA-Z0-9_] range and this breaks the bmake tests that
run as part of bootstrapping bmake.
This can be reverted when the bmake tests have been updated.
This makes it possible to compile on non-FreeBSD systems since make will
usually be GNU make there. Even if they include bmake, it will often
either be a broken version or too old to build FreeBSD.
This should be the last commit needed to compile FreeBSD on Linux+macOS.
After over two years, I've finally managed to upstream all our local CheriBSD
changes to allow building on Linux (and as a result of being reviewed by more
people they are slightly less ugly than they were before).
It should now be possible to run the following to build on Linux+macOS if you
have LLVM/Clang 10 or newer installed:
MAKEOBJDIRPREFIX=/somewhere ./tools/build/make.py TARGET=amd64 TARGET_ARCH=amd64 buildworld
I have only tested macOS 15, Ubuntu 18.04 and openSUSE Leap, but other Linux
distributions might also work (as long as they ship a recent GLibc and compiler).
