libstdc++: Fix linker script to remove conflicting patterns

This should fix a bootstrap error on Solaris, due to some of the new
symbols matching old patterns as well as new ones.

libstdc++-v3/ChangeLog:

	* config/abi/pre/gnu.ver (GLIBCXX_3.4.21): Tighten patterns
	for old <sstream> symbols some more.
