The combination of those two would seem to suggest a complication: when 
you configure for a configuration needing multiple sets of names in 
gnu/lib-names.h, you need multiple sets of sysdeps directories, one for 
each variant going in gnu/lib-names.h so the appropriate shlib-versions 
file can be found.  So the specification of applicable variants (that 
might share a header directory) needs to be linked in some way to the code 
computing sysdeps directories so that the list can be computed for each 
variant, when each variant uses its own shlib-versions file in its own 
sysdeps directory.
