[Marc Gauthier]

This patch allows recognizing Xtensa processor variants.
The corresponding change to config.{sub,guess} is already in place.

Thanks,
-Marc

 This target is for Xtensa systems running GNU/Linux.  It supports ELF
 shared objects and the GNU C library (glibc).  It also generates
 position-independent code (PIC) regardless of whether the
 @option{-fpic} or @option{-fPIC} options are used.  In other
