MSVC Compiler Flags Incorrectly Passed to Linker (Regression)

[TriceHelix]

This is a regression of #2209.

Configure using these flags:
--os=windows --cc=msvc --disable-shared-library --msvc-runtime=MT
...and build. This produces the following linker error:
LINK : fatal error LNK1146: no argument specified with option '/MT'

It seems identical to the issue from 5 years ago and occurs on version 3.6.1 (lastest release).

Confirmed. This is being addressed as a side-fix in #4255. Perhaps we should extract that and merge it independently, @randombit?
