Comment (by Phyx-):

 For whatever reason `libgcc` is not passed to the linker by gcc. Would
 need to look at what the profiling options pass to the linker.

 In any case you can work around it by passing `-lgcc` to ghc or add
 `extra-libraries: gcc` to your cabal file. We should probably add `gcc`
 explicitly to the libraries list of the rts.
