This update for gcc7 to 7.3 release fixes the following issues:

- Update to GCC 7.3 release and further updated to gcc-7-branch head (r258812).
- The Spectre v2 mitigation patch for s390x is now included. [bsc#1083946]
- Adds backport of x86 retpoline support via -mindirect-branch=, -mfunction-return= and friends. [bsc#1074621]
- Update includes a fix for chromium build failure.  [bsc#1083290]
- Various AArch64 compile fixes are included:

  * Picks fix to no longer enable -mpc-relative-literal-loads by default
    with --enable-fix-cortex-a53-843419.
  * Enable --enable-fix-cortex-a53-843419 for aarch64.  [bsc#1084812] [bsc#1087930]
  * Enable --enable-fix-cortex-a53-835769 for aarch64.
  * Contains fix for PR82445 which is about a RPI1 bootloader miscompile. [bsc#1061667]
  * Fixed bogus stack probe instruction on ARM. [bsc#1068967]

- Revert the ios_base::failure ABI back to compatible behavior with the default ABI.  [bsc#1087550]

- Fix nvptx offload target compiler install so GCC can pick up
  required files.  Split out the newlib part into cross-nvptx-newlib7-devel
  and avoid conflicts with GCC 8 variant via Provides/Conflicts
  of cross-nvptx-newlib-devel.
