powerpc: getEnvironment empty when run in GHCi
Hi,
on powerpc (only), with ghc-7.8, we have this:
```
$ cat env.hs
import System.Environment
main = getEnvironment >>= print
$ runhaskell env.hs
[]
$ ./env
[("RESET","\\e[0m")...
```
This breaks the test suite of shake. Does anyone feel like investigating this?
