Fixing link failure of compiler on ia64 ('-Wl,' prefixed value passed directly to ld)
/usr/bin/ld -Wl,--relax -r -o dist-stage1/build/HSghc-6.10.4.o \ dist-stage1/build/BasicTypes.o dist-stage1/build/DataCon.o ... /usr/bin/ld: unrecognized option '-Wl,--relax'
If we just drop '-Wl,' part it will not help as '-r' and '--relax' are incompatible.
Looks like '-Wl,--relax' was skipped by earlier binutils' ld as unknown option.
Removing ia64 specific path.
