Fix GMP cross-compilation when Wine installed (#8645)

When Wine is installed on the system, our current invocation of GMP's
`configure` fails. To fix the issue, we pass `CC_FOR_BUILD` that is used
to compile build-time programs. When compiling GMP with `--enable-cxx`,
it also seems to be necessary to pass `--build` to make `configure`
pass. Passing `--build` for cross-compilation builds is also recommended
by the [GMP documentation](https://gmplib.org/manual/Build-Options).
