configure: exit 77
```

Start by reproducing the x64-uwp failure with `vcpkg install jemalloc[*]`, then read ports/jemalloc/portfile.cmake and the generated configure logs named in the report. Trace why the C compiler test fails under the UWP toolchain and check the existing fix-configure-ac.patch and preprocessor.patch. Done means jemalloc configures and builds successfully for x64-uwp.
