libstdc++: Tweak linker script to avoid conflict on Solaris

The new symbols for the _M_construct<bool> function template match an
existing pattern in the GLIBCXX_3.4.21 version, as well as the intended
pattern in the GLIBCXX_3.4.34 version. That causes a linker error on
Solaris.

libstdc++-v3/ChangeLog:

	* config/abi/pre/gnu.ver (GLIBCXX_3.4.21): Make
	std::basic_string::_M_construct patterns more precise.
