Stub out multiarch detection in lang/python3X ports for clang 13
During an exp-run for llvm 13 (see bug 258209), it turned out that
lang/python3([6-9]|10) do not build with clang 13.0.0 [1][2][3][4][5]:

ModuleNotFoundError: No module named
'_sysconfigdata_m_freebsd14_x86_64-unknown-freebsd14'
*** Error code 1
The reason this breaks with clang >=3D 13, is that it now started supportin=
g the
-print-multiarch option, but in its output it adds a major.minor version
number, for example x86_64-unknown-freebsd14.0. The dot confuses Python, as=
it
appends the multiarch name to the sysconfig module name, and then can't load
the resulting _sysconfigdata__freebsd14_x86_64-unknown-freebsd14.0.py file:
ModuleNotFoundError: No module named
'_sysconfigdata__freebsd14_x86_64-unknown-freebsd14'
Since we do not support multiarch, and the configure script has no way to
disable the multiarch check, I would like to propose to just stub it out du=
ring
post-patch, as per the attached diff.
