Optionally disable building libraries with visibility attributes (bug #59820). * configure.ac: Add argument --disable-lib-visibility-flags to manually disable building and linking Octave libraries with visibility attributes. * Makefile.am: Use compiler flags for symbol visibility according to configure result. * oct-conf-post.in.h, build-aux/mk-octave-config-h.sh: Set preprocessor macros with visibility attributes to empty optionally.
