Scripts: Put /usr/xpg4/bin to the beginning of PATH on Solaris.
This adds a configure option --enable-path-for-scripts=PREFIX which defaults to empty except on Solaris it is /usr/xpg4/bin to make POSIX grep and others available. The Solaris case had been documented in INSTALL with a manual fix but it's better to do this automatically since it is needed on most Solaris systems anyway. Thanks to Daniel Richard G.
