I've done some refactoring while debugging #209.
* Unused file `pmb/build/crosscompiler.py` removed (that was a
left over from `_pmb_build_in_native_chroot` hack
* Do verbose logging in distccd, when `pmbootstrap --verbose` is
being invoked
* Restart distccd, when the commandline has changed (e.g. when the
currently running version was not verbose, and the new one is
verbose.) Prior to this change, it only got restarted, when the
architecture changed (so it did not allow changing the job count
on the fly for example).
* Insert missing whitespace in arguments help.
* Fix hardcoded `armhf` in pmb/aportgen/binutils.py
* Generate aports: `binutils-aarch64`, `musl-aarch64`, `gcc-aarch64`
* Distccd: Remember the cross-compiler architecture (currently armhf
or aarch64), that the current distccd is running as, and restart
distccd with the correct architecture, in case a different arch
is needed than what it is currently running as. (Depending on the
cross-compiler arch, the PATH variable gets adjusted before
starting distccd)
* Testcases: add aport generation for aarch64, add cross-compiling
to aarch64
* pmb/parse/arch.py: Add aarch64 to the mapping
