[issue23287] ctypes.util.find_library needlessly call crle on Solaris

[Jeff Quast]

John, What do you think of the patches attached to http://bugs.python.org/issue20664 ?

"crle is not needed at all because the default library path is
a constant on Solaris"

I don't believe this to be true, source? crle is absolutely needed to add additional library lookup paths on Solaris, did this recently change?

crle is most certainly especially in regards to zones: a zone is unable to modify any of the system library paths, it wouldn't be able to install any new libraries in those given paths (/usr/lib and /lib are often shared read-only by the global zone), and crle must be used to add a library path to a writable mountpoint, such as /usr/local/lib, and often /opt and other various deviations must occur to accommodate gnu tools, etc.
