Contrary to abuild, pmbootstrap only installs makedepends, and
keeps the installed packages around - both hacks save lots of time.
However, they may introduce missing makedepends in the APKBUILDs,
that the authors of the APKBUILDs do not notice because it works
for them.
This PR adss a strict mode, which will always clean the chroots
before building a package, and also remove all installed dependencies
after the package was built. You can use the following syntax to
only zap once, but build many packages at once:
`pmbootstrap build --strict hello-world 0xffff heimdall`
It also builds dependencies properly without leaving makedepends
behind.
The following message will be printed out now, in case you attempt
to build a package for an architecture, that is not specified in
the "arch=..." line inside the APKBUILD:
ERROR: Architecture 'aarch64' is not supported for this package.
Please add it to the 'arch=' line inside the APKBUILD and try again:
/path/to/APKBUILD
