perf: Fix to obey LD failure on qemux86-64

Browse Source 
When built on an i686 host for qemux86-64 without the
fix to obey LD and it fails:

/scratch/dogwood/toolchains/x86_64/bin/i686-pc-linux-gnu-ld:
Relocatable linking with relocations from format elf64-x86-64
(/scratch/dogwood/perf-ld-test/build/tmp/work/qemux86_64-mel-linux/perf/1.0-r9/perf-1.0/fs/fs.o)
to format elf32-i386 (/scratch/dogwood/perf-ld-test/build/tmp/work/qemux86_64-mel-linux/perf/1.0-r9/perf-1.0/fs/libapi-in.o)
is not supported

This is because LD includes HOST_LD_ARCH, which contains TUNE_LDARGS,
which is -m elf32_x86_64 for x86_64. Without that, direct use of ld will fail.
