[Hat] building hat with ghc 6.4.2 under debian testing/unstable

hello, cpp from gcc 4.1.2 appears to output more whitespace than expected when generating ghcsym.out. this results in the following error during build: ~/src/other/hat-2.04.orig$ make src/other/hat-2.04.orig/lib/ix86-Linux/config:11: *** missing separator. Stop. the attached patch appears to fix this.
