hsc2hs wrapper script throws away $HSC2HS_EXTRA's value when specified C compiler to use
hsc2hs wrapper script ignores default flags to build 32bit binary when specified C-compiler to use even if it was gcc.
This become a problem when building packages with Cabal. As usual, Cabal passes --cc=/path/to/gcc to hsc2hs. So default flags are ignored, built packages are broken.
I edited script to fix this problem. I think it's ugly fix, but it works.
