[issue4120] Do not embed manifest files in *.pyd when compiling with MSVC

[Andre Heider]

Skipping the mt.exe call seems fine to me, but there's another solution
which might be better:

The automatic manifest binding comes from a "#pragma
comment(linker,"/manifestdependency:" directive in crtdefs.h. That can
be disabled by setting _CRT_NOFORCE_MANIFEST. This way all other
manifest dependencies stay in tact and it could be set for *.pyd builds
(instead of my patch).

TCL's manifest is a different problem. I do not use tkinter, but
according to PCbuild/readme.txt it should be possible to get rid of the
CRT dependency the same way: just set _CRT_NOFORCE_MANIFEST in the nmake
line.
