Add a new USE_LIBTOOL definition that uses the libtool package instead of
pkglibtool which is now considered outdated.
USE_PKGLIBTOOL is available for backwards compatibility with old packages
but is deprecated for new packages.
- DO NOT INSTALL DOCS IN ${PREFIX}/docs. They belong in ${PREFIX}/share/doc.
- Add SEGV-preventing patch from Sleepycat's web site.
I did not enable C++ and DB 1.85 compat API in this update to make the
change during freeze time minimal; for maximum flexibility in case more
than just Sendmail wants to use this pkg!, the former should be enabled
at next update, and the latter cannot be enabled until Sleepycat adds a
fix I have sent them (or I add the fix to the patches directory).
