Details: - Implemented support for the user manually overriding the automatic subconfiguration selection that happens at runtime. This override can be requested by setting the BLIS_ARCH_TYPE environment variable. The variable must be set to the arch_t id (as enumerated in bli_type_defs.h) corresponding to the desired subconfiguration. If a value outside this enumerated range is given, BLIS will abort with an error message. If the value is in the valid range but corresponds to a subconfiguration that was not activated at configure-time/compile-time, BLIS will abort with a (different) error message. Thanks to decandia50 for suggesting this feature via issue #451. - Defined a new function bli_gks_lookup_id to return the address of an internal data structure within the gks. If this address is NULL, then it indicates that the subconfig corresponding to the arch_t id passed into the function was not compiled into BLIS. This function is used in the second of the two abort scenarios described above. - Defined the enumerated error code BLIS_UNINITIALIZED_GKS_CNTX, which is returned for the latter of the two abort scenarios mentioned above, along with a corresponding error message and a function to perform the error check. - Added cpp macro branching to bli_env.c to support compilation of the auto-detect.x executable during configure-time. This cpp branch is similar to the cpp code already found in bli_arch.c and bli_cpuid.c. - Cleaned up the auto_detect() function to facilitate easier maintenance going forward. Also added a convenient debug switch that outputs the compilation command for the auto-detect.x executable and exits.
