Comment (by steve@…):

 This isn't a GCC bug.  Use of -march is expected to produce code suitable
 for *only* the target CPU architecture.  Usage of -march or other -m flags
 to enable features from within build-systems is incorrect usage of the
 compiler.  The build-system should detect which features are available on
 the configured compiler, not the other way around.  Generic code should be
 generated with with a specific minimum requirement in mind, but should
 always be limited to whatever the build toolchain is constrained by.
