 did not change any settings per architecture here, but it seems that ghc
 by default builds GHC without dynamic libraries?

 Yeah, there is a blacklist of bad platforms:
 {{{
 # apt-get source ghc

 # grep -A10 NoSharedLibsPlatformList ghc-7.8.4/mk/config.mk.in
 NoSharedLibsPlatformList = powerpc-unknown-linux \
         x86_64-unknown-mingw32 \
         i386-unknown-mingw32 \
         sparc-sun-solaris2 \
         sparc-unknown-linux \
         mips-unknown-linux \
         mipsel-unknown-linux
 }}}

 On 7.10 it does not contain linux targets.

 I've completely forgot that upstream ghc was released before PPC -fPIC fix
 went upstream fa31e8f4a0f853848d96549a429083941877bf8d after 7.8.4 release
 :(
 You might like to apply this as well
