Cleanly setting C compiler options when building RTS

[Matthew Pickering]

Hi Siddharth,

The correct way is to create a custom flavour with something like the
following in.

grts = quickFlavour { name = "grts", args = args quickFlavour <>
(builder Cc ? package rts ? arg "-g3" <> arg "-O0") }

Cheers,

Matt
