Description: support mixed machine capabilities without impeding the build
 This allows one to build the package with almost any combination of machine
 capabilities.  The initial issue was reported against -march=x64-64-v2, but
 the present patch extends to v3, and probably any combination thrown by a
 -march=native.  The issue seems tied to the way the build process is modified
 by debian, so may not be very relevant cherry picked upstream.
 .
 Diagnostics information is kept around just in case, for convenience.
