Fix --diable-shared --enable-plugins build breakage
Directories that don't use libtool need to add -ldl (on most *nix hosts) to provide dlopen for libbfd. config/ * plugins.m4 (AC_PLUGINS): If plugins are enabled, add -ldl to LIBS via AC_SEARCH_LIBS. gdb/ * acinclude.m4 (GDB_AC_CHECK_BFD): Don't add -ldl. * config.in: Regenerate. sim/ppc/ * configure.ac: Invoke AC_PLUGINS. * config.in: Regenerate. and regen lots of configure files.
