Comment(by carter):

 the way the haskell platform papers over this on mac is with
 https://github.com/haskell/haskell-
 platform/blob/master/src/macos/PatchSettings.hs  to adjust the ar and gcc
 name settings in the ghc settings file.

 which effectively hides / papers over the issue that the -pgmc CCName flag
 doesn't seem to quite work

 Hrm, it looks like my other issue comes from the {{{as}}} that apple
 provides not supporting AVX!

 I tried the workaround  using "gcc -c" or "clang -c"  or "gcc -c
 -Xassembler" my assembler via the -pgma flags, but that didn't fix it /
 didn't work

 instead, i used the directions in this stack overflow
 http://stackoverflow.com/questions/9840207/how-to-use-avx-pclmulqdq-on-
 mac-os-x-lion to an {{{as}}} wrapper i've put on my PATH.  This works.


 That still leaves the matter that -pgmc doesn't fully override the ghc
 SETTINGS file though, and that my attempt at using -pgma didn't work
 either
