New description:

 when compiling i get the warning
 {{{
 /usr/bin/d.gold: warning: cannot scan executable section 1 of .....
 transformers-04.3.0a... for Cortex-A8 erratum because it has no mapping
 symbols.
 }}}
 there are some informations on the web on the cortex-a8 erratum, but i
 cannot see how i could apply them. should the compiler be recompiled? i
 installed from the debian distribution.
 the hardware is a cubietruck.
 i observe that compilation, especially the phase of preparing the
 configuration in cabal takes very long - perhaps this is related to this
 problem. the resulting code is ok and runs with expected speed.

 thank you for producing a full ghc for arm!
 andrew
