+Subject: [PATCH 1/2] BLD: provide explicit control over cpu-baseline detection
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add a new `cpu-baseline-detect` feature flag that can be used to more
+precisely control the use of CPU baseline detection.  This can be used
+by packages to more precisely control used SIMD code independently
+of compiler flags specified.  The option follows typical feature
+semantics -- with `auto` preserving the current behavior of enabling
+when relevant compiler flags are found, `enabled` forcing it on
+based on the implicit compiler defaults, and `disabled` forcing it off.
+
