configury changes to make ld plugin support controlled by --enable-plugins
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. Delete
plugin checks now done in config/plugins.m4.
* config.in: Regenerate.
* configure: Regenerate.
