Well, we already can add flags via "Common fixed flags". I think all we need is "override" option that would avoid adding platform flags before adding these fixed.

As far as I know, there is a possibility to override platform related flags. This feature is implemented in LocalHost::AddFlags and LocalHost::HasPlatformFlag methods ^{[1, 2, 3]}.
For example, possible to generate Makefile(s) for WIN32 platform, e.g.:

./umk uppsrc ide CLANG -r -M=Makefile +WIN32,GUI

or FreeBSD:

./umk uppsrc ide CLANG -rs -M=BSDMakefile +POSIX,BSD,FREEBSD,GUI

or Linux:

./umk uppsrc ide CLANG -rs -M=GNUMakefile +POSIX,LINUX,GUI

etc.

There is just a need to use correct build method for them. But I didn't test this for cross-platform/remote build(s), just for Makefile generation.

May suggest to add "OSX" flag to platformFlags also (based on order of appearance in LocalHost::AddFlags method). Patch attached.
