Ignore the build host Python interpreter configuration when
compiling portable "abi3" extension modules.
Such extensions should not depend on a concrete Python version
or build configuration by design.
Maturin already does this when building "abi3" extension wheels
by defining
PYO3_NO_PYTHON=1
for Cargo when anabi3-py3*
feature is detected.
Closes #2292
