Instead of battling pip to install a wheel, use installer. Installer does one thing, so it's faster and easier to work with. This means setuptools, pip, and wheel are no longer part of the bootstrap phase, so they can be built normally. To avoid sysroot file conflicts these three recipes can't install .pyc files to the native sysroot. We currently patch pypa/installer to allow us to override the interpreter used, which means we can drop the interpreter seding. We don't need to recompile any Python which is found in $bindir as Python doesn't actually load those files. Across a build of oe-core, the only differences between using pip and installer are: - the .dist-info/RECORD files are ordered differently - the .dist-info/REQUESTED and INSTALLER files are not created - the hashbang in native scripts is "/usr/bin/env nativepython" instead of pointing directly at the native sysroot python3.
