Revision 409123

MFH: r409114

Update to 0.2.15.

0.2.15 was released in October 2015.
Release notes: http://www.openblas.net/Changelog.txt

This update introduces support for new CPU architectures, such as Intel's
Broadwell and Skylake. In practice, this means people using those architectures
can actually build the port now (OpenBLAS seems to do some CPU-detection that
cannot be easily turned off and refusing to build on unrecognized CPUs).

Port changes:
- Reorganize a few variables in Makefile.
- Refresh patches.
