Cache qt_config_compile_test results

Browse Source 
Inside qt_config_compile_test we use two different calls:
check_cxx_source_compiles when given code, and try_compile when
given a project.

The former caches its results, while the latter does not, which means
that the try_compile calls are re-executed on each reconfigure.

Do what check_cxx_source_compiles does internally, and don't rerun
the try_compile calls if the results were computed once.
