I've not tried non-EABI NPTL, going EABI will of course break everything.. ;-)
Maybe somebody here has..?

Debian is working on an ARM EABI/NPTL distribution I don't know if that's much
help to you though?

If you want to continue targetting strongarm you may have to tweak binutils a
little.  I'll take a look if I get a moment.  StrongARM is the closest common
architecture for them all then?  You maybe best to just build a completely
generic ARM toolchain with mutlilib and use multiple spec files?
