libga68: Remove redundant CHECK_ATTRIBUTE_VISIBILITY macro

Use the shared macro from config/visibility.m4.

libga68/ChangeLog:

	* Makefile.in: Regenerate.
	* acinclude.m4: Delete LIBGA68_CHECK_ATTRIBUTE_VISIBILITY.
	* aclocal.m4: Regenerate.
	* configure: Regenerate.
	* configure.ac: Use GCC_CHECK_ATTRIBUTE_VISIBILITY instead of
	LIBGA68_CHECK_ATTRIBUTE_VISIBILITY.
