7315,Link error while compiling executables,bgamari,,"
On GHC master (ef786b6cbc5f67a673bf8c10be5311317c1e7b88) attempting to build any executable results in a linker error. For instance, `cabal install cmdargs` results in,
{{{

     cabal: Error: some packages failed to install:
     cmdargs-0.10 failed during the building phase. The exception was:
     ExitFailure 1
}}}
Yet transformers appears to be installed (although the version suffix doesn't appear to match),
