[profile] Allow profiling to be globally enabled or disabled
As with assertions, profiling is enabled for objects built with any
debug level (including an explicit debug level of zero).
Allow profiling to be globally enabled or disabled by adding PROFILE=1
or PROFILE=0 respectively to the build command line.
