This brings our math/libflame to a recent state, as opposed to the outdated one before. Their development has moved to github. Configure it as a LAPACK library and to use an external BLAS to eventually support a blaslapack:flame together with math/blis. Please note that this should be used with caution in production until the port is better tested!
Their make system now generates a large quantity of object files to link which I found to only work with a recent linker (hence the requirement for recent CURRENT with lld default). Since this is a numerical library, some caution is required before we can enable it for other architectures. Patches were generated by hand as makepatch failed to work properly.
