ARM illegal instruction

Where can I find a list of "supported subspecies" of arm
processors for glibc?  If I read the configure script right
then it would depend on directories, which don't seem to
exist.  So either there is no specific processor support, or
(more likely) I'm reading it wrong.  If I ever figure out
the right combination of words to query Google that might
help too, but for now that's a dead end too.

I've had this when the C compiler was built for armv4t as it should,
but the libraries built for the (unfortunately) default CPU of armv5t,
which means clz instructions.

try a shot of --with-cpu=
