Comment (by ezyang):

 Sorry about not following up sooner. If any object that will be linked in
 has executable stack set, then the whole binary will have an executable
 stack. So it would seem HSbase*.o is at fault.  However, in GHC HEAD I
 have no problem:

 {{{
 ezyang at javelin:~/Dev/ghc-build-alloc$ readelf -W -l libraries/base/dist-
 install/build/libHSbase-4.7.0.0-ghc7.7.20130830.so  | grep GNU_STACK
   GNU_STACK      0x000000 0x0000000000000000 0x0000000000000000 0x000000
 0x000000 RW  0x8
 }}}

 Perhaps some library HSbase is using has an executable stack?
