MSYS/MinGW Makfiles: Select the compiler occurring first in PATH

Extend the change from commit e01990999a (Ninja: On Windows, select the
compiler occurring first in PATH, 2020-04-17, v3.18.0-rc1~291^2) to
apply to the MSYS/MinGW Makefiles generators too.  Drop the implied
`gcc` and `g++` default compilers.  This allows MinGW/Clang environments
to work out of the box.
