                                                  ^^^^^
Shouldn't it be '-fPIC'?

Unfortunately I can't try the patch on the same machine because the
icc license has expired a few days ago (it was just an evaluation
version). However I have access to another machine with icc installed;
this is a different version, but it's also a version that doesn't
accept -KPIC, so I assume the test will be significant.
