AM_CFLAGS seems to do the trick, e.g., 

  $ make AM_CFLAGS='-Wc,-tp=k8-32'

I am using the latest Libtool from the git repo (Fri Mar 20 16:42:25),
with the above "-tp" patch and libtoolize is stuck pegging my CPU at
99%.  I assume I should have been applying the "-tp" patch to a stable
Libtool version, e.g., 2.2.6?

Thanks,
