1f527a93b9
Details:
- Re-enabled the changes made in fb93d24.
- Defined BLIS_ENABLE_SYSTEM in bli_arch.c, bli_cpuid.c, and bli_env.c,
all of which needed the definition (in addition to config_detect.c) in
order for the configure-time hardware detection binary to be compiled
properly. Thanks to Minh Quan Ho for helping identify these additional
files as needing to be updated.
- Added additional comments to all four source files, most notably to
prompt the reader to remember to update all of the files when updating
any of the files. Also made the cpp code in each of the files as
consistent/similar as possible.
- Refer to issues #532 and PR #546 for more history.
