[PATCH 1/7] OpenMP 4.0 offloading infrastructure: configure and make
* configure: Regenerate.
* configure.ac (--enable-as-accelerator-for)
(--enable-offload-targets): New configure options.
gcc/
* Makefile.in (real_target_noncanonical, accel_dir_suffix)
(enable_as_accelerator): New variables substituted by configure.
(libsubdir, libexecsubdir, unlibsubdir): Tweak for the possibility of
being configured as an offload compiler.
(DRIVER_DEFINES): Pass new defines DEFAULT_REAL_TARGET_MACHINE and
ACCEL_DIR_SUFFIX.
(install-cpp, install-common, install_driver, install-gcc-ar): Do not
install for the offload compiler.
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac (real_target_noncanonical, accel_dir_suffix)
(enable_as_accelerator): Compute new variables.
(ACCEL_COMPILER): Define if the compiler is built as the accel compiler.
(OFFLOAD_TARGETS): List of target names suitable for offloading.
(ENABLE_OFFLOADING): Define if list of offload targets is not empty.
gcc/cp/
* Make-lang.in (c++.install-common): Do not install for the offload
compiler.
gcc/doc/
* install.texi (Options specification): Document
--enable-as-accelerator-for and --enable-offload-targets.
gcc/fortran/
* Make-lang.in (fortran.install-common): Do not install for the offload
compiler.
libgcc/
* Makefile.in (crtoffloadbegin$(objext)): New rule.
(crtoffloadend$(objext)): Likewise.
* configure: Regenerate.
* configure.ac (accel_dir_suffix): Compute new variable.

libgomp/
* config.h.in: Regenerate.
* configure: Regenerate.
* configure.ac: Check for libdl, required for plugin support.
(PLUGIN_SUPPORT): Define if plugins are supported.
(enable_offload_targets): Support Intel MIC targets.
(OFFLOAD_TARGETS): List of target names suitable for offloading.
lto-plugin/
* Makefile.am (libexecsubdir): Tweak for the possibility of being
configured for offload compiler.
(accel_dir_suffix, real_target_noncanonical): New variables substituted
by configure.
