Parser fails when cabal runs configure in v2-repl

[pranaysashank]

In my project, hie-bios fails with

Failed to parse result of calling cabal\nChecking for gcc .. \n.....

cabal seems to be outputting the result of it's configure step before calling ghc --interactive

I got around this with modifying the shell script to

and filtering it out in processCabalWrapperArgs
