libstdc++: Disabling AC_LIBTOOL_DLOPEN check if building with avr-libc

The AC_LIBTOOL_DLOPEN checks were previously disabled for newlib targets.
The patch applies similar logic to avr-libc based builds.

libstdc++-v3/ChangeLog:

	* configure.ac: Skip AC_LIBTOOL_DLOPEN check if avr-libc is used.
	* configure: Regenerate.
