The long double compat symbols are producing warnings, this
suppressess them.

	* config/locale/gnu/c_locale.cc [_GLIBCXX_LONG_DOUBLE_COMPAT]: Ignore
	-Wattribute-alias warnings.
	* src/c++11/istream-inst.cc: Likewise.
	* src/c++11/locale-inst.cc: Likewise.
	* src/c++11/ostream-inst.cc: Likewise.
	* src/c++11/wlocale-inst.cc: Likewise.
	* src/c++98/hash-long-double-tr1-aux.cc: Likewise.

Tested powerpc64le-linux, committed to trunk.
