This also makes --enable-plugins default to on for hosts that can support plugins, so we have consistent lto toolchain support. The ACX_LARGEFILE moves aren't strictly necessary, but are harmless and will be necessary if plugin support is extended to more hosts via libtool's dlopen support. I started down that path then decided it was more work than I was interested in doing. (ACX_LARGEFILE invokes AC_PLUGINS.) config/ * plugins.m4: Test for dlfcn.h or windows.h here to set default for --enable-plugins. Report error if someone tries to enable plugins on a host we don't support. bfd/ * configure.ac: Delete redundant plugin related checks. * configure: Regenerate. binutils/ * configure.ac: Move ACX_LARGEFILE after LT_INIT. * config.in: Regenerate. * configure: Regenerate. gas/ * configure.ac: Move ACX_LARGEFILE after LT_INIT. * config.in: Regenerate. * configure: Regenerate. gprof/ * configure.ac: Move ACX_LARGEFILE after LT_INIT. * configure: Regenerate. * gconfig.in: Regenerate. ld/ * configure.ac: Move AC_PROG_CC and other macros earlier.
