 After building a compiler with the `prof` flavour. I tried to use it with
 the `-xc` option.

 {{{
 ./hadrian/build.sh --flavour=prof
 _build/stage1/bin/ghc A.hs +RTS -xc
 }}}

 But apparently

 {{{
 ghc: the flag -xc requires the program to be built with -prof
 }}}

 So it seems that the `prof` flavour is broken.
