profiling is not yet supported by clang irrc. the same goes for
cross-compiling. both features will be introduced in one of the next releases.

clang is still missing a few gcc features, however i think that's obvious
taking into account that gcc exists way longer than clang. however it's also
obvious that in a few years gcc will be completely replaced by clang as main
open source C/C++ compiler, since it offers tons of advantages and only very
few disadvanteges.

cheers.
