Port the OpenMP runtime to FreeBSD along with associated build system changes.

Also begin to generalize affinity capabilities so they aren't tied explicitly
to Windows and Linux.

The port builds with stock clang and gmake and has no additional runtime
dependencies.

All but a handful of the validation suite tests are now passing on FreeBSD 10
x86_64.

No version of clang installed by XCode, ToT or otherwise recognizes the flag
'-no-intel-extensions' and more recent versions error out on it.

Prospectively conditionalize the flag behind "icc" to fix the mainline build
with clang.

check-tools.pl was hard-wired to expect the Apple compiler version string which
doesn't make much sense, especially for a LLVM project.

The correctness and value of these compiler version checks still isn't clear
following this build fix but they are retained for now.

gcc/g++ don't exist on modern OS X development environments so the failed
checks for gcc were causing the build to break even with 'make compiler=clang'.

(The rationale for the check refers to a file 'touch-test.c' which no longer
exists in the codebase.)

This release use aligns with Intel(r) Composer XE 2013 SP1 Product Update 2 

New features
* The library can now be built with clang (though wiht some
  limitations since clang does not support 128 bit floats)
* Support for Vtune analysis of load imbalance
* Code contribution from Steven Noonan to build the runtime for ARM*
  architecture processors 
* First implementation of runtime API for OpenMP cancellation

Bug Fixes
* Fixed hang on Windows (only) when using KMP_BLOCKTIME=0
