* ld.texinfo (VERSION scripts): Symbol names are globbing patterns.

Browse source 
* ldgram.y (lang_new_vers_regex):  Rename to lang_new_vers_pattern;
	the pattern in question is not a regexp.
	* ldlang.c:  Likewise.
	* ldlang.h:  Likewise.
	* ldlex.l (V_IDENTIFIER):  Allow '[', ']', '-', '!', and '^' also.

version node defined is @samp{VERS_1.1}; it has no other dependencies.
The script binds the symbol @samp{foo1} to @samp{VERS_1.1}. It reduces
a number of symbols to local scope so that they are not visible outside
of the shared library.
of the shared library; this is done using wildcard patterns, so that any
symbol whose name begins with @samp{old}, @samp{original}, or @samp{new}
is matched. The wildcard patterns available are the same as those used
in the shell when matching filenames (also known as ``globbing'').
Next, the version script defines node @samp{VERS_1.2}. This node
depends upon @samp{VERS_1.1}. The script binds the symbol @samp{foo2}
