tools use some features of glob(3) that are not available on
all systems.
* Always include the NetBSD vis(3) in libnbcompat, since vis(3)
is not really standardized, and the vis(3) present on some systems
is different from ours.
* Always include the NetBSD MD2, MD4, MD5, RMD160, and SHA1 implementations
in libnbcompat. The host tools use features of the NetBSD versions
which aren't present on all systems that include those functions.
* Add a check for random(3) -- the Heimdal host tools want it.
* Add a check for termios.h -- the Heimdal host tools want it.
* Update the README to indicate the current state of building the
host tools on Solaris 8 (for SPARC).
