offload-defaulted: Config option to silently ignore uninstalled offload compilers
If configured with --enable-offload-defaulted, configured but not installed
offload compilers and libgomp plugins are silently ignored. Useful for
distribution compilers where those are in separate optional packages.

ChangeLog:
* configure.ac (--enable-offload-defaulted): New.
* configure: Regenerate.
gcc/ChangeLog:
* configure.ac (OFFLOAD_DEFAULTED): AC_DEFINE if offload-defaulted.
* gcc.c (process_command): New variable.
(driver::maybe_putenv_OFFLOAD_TARGETS): If OFFLOAD_DEFAULTED,
set it if -foffload is defaulted.
* lto-wrapper.c (OFFLOAD_TARGET_DEFAULT_ENV): Define.
(compile_offload_image): If OFFLOAD_DEFAULTED and
OFFLOAD_TARGET_DEFAULT is in the environment, don't fail
if corresponding mkoffload can't be found.
(compile_images_for_offload_targets): Likewise. Free and clear
offload_names if no valid offload is found.
* config.in: Regenerate.
* configure: Regenerate.
libgomp/ChangeLog:
* configure.ac (OFFLOAD_DEFAULTED): AC_DEFINE if offload-defaulted.
* target.c (gomp_load_plugin_for_device): If set and if a plugin
can't be dlopened, silently assume it has no devices.
* Makefile.in: Regenerate.
* config.h.in: Regenerate.
* configure: Regenerate.
