Support reusing the wheels built for earlier Python implementations
if they are compatible with the subsequent implementations being built.
This includes pure Python wheels in packages that do not set
DISTUTILS_EXT, and stable ABI wheels.

+# @DESCRIPTION:
+# If set to a non-empty value, the eclass is allowed to reuse a wheel
+# that was built for a prior Python implementation, provided that it is
+# compatible with the current one, rather than building a new one.
+#
+# This is an optimization that can avoid the overhead of calling into
+# the build system in pure Python packages and packages using the stable
+# Python ABI.
