 On PowerPC/Linux, the `perf` build is failing for the file
 `compiler/cmm/PprC.hs` with a large number of errors like:

 {{{
 tmp/ghc29102_0/ghc_3.s:310927:0: error:
      Error: unsupported relocation against x0

 tmp/ghc29102_0/ghc_3.s:310938:0: error:
      Error: unsupported relocation against x0

 tmp/ghc29102_0/ghc_3.s:310959:0: error:
      Error: unsupported relocation against x0
 }}}

 All of the above error lines are of the form:

 {{{
 stwu    x0, 1 ,  13
 }}}
