[issue38989] pip install selects 32 bit wheels for 64 bit python if vcvarsall.bat amd64_x86 in environment

Besides the fact the MSVC's target platform isn't really related to the 
architecture for dependencies being installed, I'm not sure VSCMD_ARG_TGT_ARCH 
is an appropriate variable to look at in the first place. It doesn't seem to be 
at all documented, and (from looking at the implemenation) it seems to be meant 
as how parse_cmd.bat communicates with vcvars.bat, dotnet.bat, winsdk.bat, etc 
(these are all sub-programms that make up vcvarsall.bat)

I think %PLATFORM% (which generally ends up set equal to %VSCMD_ARG_TGT_ARCH% 
once vsdevcmd\ext\vcvars.bat has done its thing) is might be a better variable 
that cross-compiling should actually look at when it wants to know what 
architecture MSVC will compile to.

[issue38989] pip install selects 32 bit wheels for 64 bit python if vcvarsall.bat amd64_x86 in environment

Just to link the various pieces together: I think 

https://bitbucket.org/pypa/distlib/src/2d145da7cb42590039fbd56a9ab764d5d4716a98/distlib/wheel.py#lines-53

is the place in distlib that's being breaking pip due to redefining 
distutils.util.get_platform() as the cross-compile target architecture  rather 
than the build architecture.

https://docs.python.org/3/distutils/apiref.html doesn't show it as a documented 
public function, but the commit Ryan linked did introduce a new 
get_host_plaform() that matches the old behavior; if that became public and 
distlib used itinstead (conditional on the python version?) that would also be 
a way to fix the symptom Ryan noted (pip now choosing the wrong wheel to 
install).

I don't know how the pieces here fit together well enough to now which side 
should change.

@zooba: adding you to the Cc since it was your comments at 
https://github.com/python/cpython/pull/11774#discussion_r254461961 that seem to 
have led to the decision to re-define get_platform, maybe you have some 
relevant context?
