Both Darwin-GNU and Darwin-icc need the fix.

IIRC, Apple's port of GCC documented the -headerpad_max_install_names
flag as the way pad install names.  The compiler front-end happened
to implement the flag just by passing it through to the linker.  Many
of today's front-ends do not recognize this flag, so now we need to
use -Wl, to get it through.

Fixed upstream:

  http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=e498527f
  http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=eda7841f

Will be in 2.8.4.
