OpenWatcom: Add workaround for lack of error on missing library

Browse Source 
The OpenWatcom tools do not fail to link when a library is missing if no
symbols were needed from it.  This can break `try_compile` checks.
Teach `cmGlobalGenerator::Build` to pretend that the build tool returned
non-zero if the output contains the corresponding warning.
