> Another case of missing a multilib variant.

I now realize why you are talking about "multilib variant"s.

You are referring to the ARM_MULTILIB_ARCH_* defines cascade from 
score/cpu/arm/rtems/score/arm.h.

Two comments on this:
a) I consider these defines to be mis-named. They reflects groups of
sub-targets RTEMS support and have nothing to do with multilibs.

b) I consider this cascade to be harmful and to be a massive regression,
because they are trying to connect unconnected compiler features.

[Several years ago I had spend a considerable amount of time to reduce and
remove similar cascades, esp. for the powerpc, where they had proven to be
unmaintainable and to be the cause of the exception handling mess the powerpc
had suffered from.]
