This is a highly unusual situation though... but I accept what you're
saying about that for the toolchains.

Can't there be a simple answer to this?  Set %__strip to a script that
first assesses the ELF arch using objdump and then calls through to the
appropriate strip?

I see that i386 Fedora objdump says that the arm executables are of
"unknown" arch, but my arm-linux-objdump recognizes them as "arm".  It
would be a bit clunky but the basic idea of redirecting to the correct
strip based on the ELF arch will sort it out if I understood it.
