 Note: Phab:D3540 does not fix @glaubitz' issue in this ticket but fixes a
 bug that I discovered while I investigated the bug on powerpc64le Linux.
 AIX is also affected by the same bug, I think.

 As I said in comment:11 no inline assembly from `StgCRun.c` nor any code
 from `StgCRunAsm.S` should be passed to the assembler on a powerpc
 (32-bit) configured with `--enable-unregsisterised`.

 I also don't understand why `HeapStackCheck.cmm` fails. It does not
 contain any inline assembly. I wonder whether ghc does not pass the
 options required for @glaubitz' system (soft float implementation) to gcc.

 I set status `infoneeded` again while we are waiting for the input
 requested in comment:11 and comment:14.
