checked first!  Therefore, we need a hack to prepend all the
directories we give with -L to the current value of LD_LIBRARY_PATH,
thereby temporarly forming a hacked value.

Only copy LIBEXTRAS if they are given.

Svr5 doesn't use -z allextract...

-shared rather than -G.

to do it.

Note: this has only been tested on GNU-based platforms (Linux), and
needs to be tested on all others.  Additionally, it's not yet
supported on the following platforms, for lack of information:

Darwin (MacOS X)
Cygwin
OSF1/Alpha
SVR3
ReliantUNIX

Please help out with testing and the platforms we don't yet know well
enough.

Add missing semicolons.
Add a comment explaining a bunch of targets without any action lines.

Make sure test doesn't barf because of missing spaces before the

Add -lc to the list of libraries we depend upon.  Not always
necessary, but never hurts.

Add a variant of SHLIB_SOVER without the preceding period.
