Hmm.  I was talking about what rpm arch name to use for packages
compiled with VFP/iWMMXt (and noted that that decision was not entirely
trivial because they are not encoded in the ARMvN arch spec level and
so the default format does not convey enough info.)

Are you suggesting to use the target triple as the rpm arch name?

Isn't gcc-4.1.2-12.armv5l-softvfp-linux-gnueabi.rpm kind of long?

(Note that our package repo uses eabi, where vfp byte/word order
and softfloat are the default, so we don't encode those bits of
info explicitly.  The packages use 'armv5tel' as the rpm arch name.)

Yes.
