I think it is a waste of time to get this working properly in the old 
build system.

It was a good timing that the clang patches showed up along with my work 
on the new build system. I rearranged some things to make the compiler 
configurable (work in progress). The user should be able to select the 
compiler per BSP variant, e.g. build BSP A with GCC and BSP B with 
clang. For example (bsps.ini):

[sparc/erc32]
COMPILER = gcc

[riscv/rv32imac]
COMPILER = clang

To support this, I moved the GCC compiler setup to a build specification 
item:

https://git.rtems.org/sebh/rtems.git/tree/spec/build/cpukit/RTEMS-BUILD-CPUKIT-GCC.yml?h=build

All the build specification items have an "enabled-by" attribute. This 
way we can enable/disable compiler flags based on the GCC/clangs selection.
