[Bro-Dev] enable-debug doesn't work on FreeBSD

I'd like to keep Bro's use of use of CMAKE_BUILD_TYPE profiles to automatically determine the right flags for the job based on the compiler being used.  Adding a hack, exclusive to FreeBSD, to set default compiler flags isn't great since this isn't a general platform problem, just a problem with the port of CMake.

I think I understand why they did it -- it makes it easier for port maintainers to arrest full control of compile flags without patching upstream sources of projects that use build profiles.  But that approach doesn't seem to play nice when users are trying to build software outside the port system.  Taking the issue up with the CMake port maintainer might be best for now.
