Details: - Added support for libmemkind to configure. configure attempts to detect the presence of libmemkind by compiling a small program containing #include <hbwmalloc.h> and a call to hbw_malloc(). If successful, it is assumed that libmemkind is present and available. If present, use of libmemkind is enabled by default, and otherwise use is disabled by default. If libmemkind is present, the user may explicitly disable use of the library by running configure with the --without-memkind option. Furthermore, a configuration may disable libmemkind, perhaps conditional on some aspect of the build system, by including -DBLIS_DISABLE_MEMKIND in the configuration's CPPROCFLAGS make variable and setting the BLIS_ENABLE_MEMKIND makefile variable, set in config.mk, to 'no'. (The knl configuration makes use of this latter feature; see below.) - If enabled at configure-time, bli_system.h will #include <hbwmalloc.h> and bli_kernel_macro_defs.h will define BLIS_MALLOC_POOL and BLIS_FREE_POOL to use hbw_malloc() and hbw_free(), respectively. - Deprecated explicit use of BLIS_NO_HBWMALLOC in config/knl/bli_family.knl.h and replaced use of -DBLIS_NO_HBWMALLOC in config/knl/make_defs.mk with -DBLIS_DISABLE_MEMKIND, which overrides (#undefs) the definition of BLIS_ENABLE_MEMKIND in bli_system.h, if it would otherwise be defined. Also, set the BLIS_ENABLE_MEMKIND makefile variable to 'no'. - common.mk now adds libmemkind to LDFLAGS if libmemkind is enabled.
