The particular system here is Darwin 8/PPC, but the same happens on Darwin 9/x86.

GNU linker scripts don't exist on Darwin (Mach-O) targets, hence testing for them on this platform is pointless.  Perhaps the code to check can be conditionalised for ELF-platforms only, which would leave the assert problem.",bug,closed,normal,,Compiler,6.12.3,fixed,,grobian@… howard_b_golden@…,MacOS X,Unknown/Multiple,Building GHC failed,,,,,
