[Bug libc/9758] New: RTLD_DEEPBIND causes separate NULL `environ'

["jan dot kratochvil at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

After some debugging ( https://bugzilla.redhat.com/show_bug.cgi?id=480504 )
found out a use of RTLD_DEEPBIND will cause NULL `environ' in the loaded library.

This is IMO a generally unexpected behavior and either `environ' should be an
exception of being shared despite RTLD_DEEPBIND or at least the man page could
make a note of it.

Tested on: Fedora glibc-2.9-3.x86_64
