* configure: Changes for building on Solaris 10 using the

/usr/bin/xpg4/sh shell. Solaris' /bin/sh does not like test
-e. Adding break to the new shell existence testing loop so we
use the first shell in the list. Solaris wants _XOPEN_SOURCE=500
to reveal certain functions. Fix breakage in the make utility
detection, and also use the $make variable everywhere instead
of make.
