Revision 1860587

- Temporarily move x86 to use Zero in order to get a working build
- Introduce architecture restriction logic for the gdb test. (RH2041970)
- Disable on x86, x86_64, ppc64le & s390x while these are broken in rawhide.
- Replace GCC 11 patch to remove use of the register keyword with correct fix to ADLC build (JDK-8281098)
- Adjust JDK8199936/PR3533 -mstackrealign patch to instead pass -mincoming-stack-boundary=2 -mpreferred-stack-boundary=4
- Refactor build functions so we can build just HotSpot without any attempt at installation.
- Explicitly list JIT architectures rather than relying on those with slowdebug builds
- Disable the serviceability agent on Zero architectures even when the architecture itself is supported
