PR26002 undefined symbol VER_NDX_GLOBAL vs. VER_NDX_LOCAL
This patch makes undefined unversioned dynamic symbols use
VER_NDX_GLOBAL (version 1) rather than VER_NDX_LOCAL (version 0).
There really isn't much use for an undefined local dynamic symbol, so
we may as well use the logically correct value in .gnu.version.
