cuda gcc conflicts not working #13462
Description
The conflicts in the the cuda build system are not working. For example, the libbeagle package uses the cuda build system.
class Libbeagle(AutotoolsPackage, CudaPackage):

...The libbeagle build will then fail with
..
/targets/x86_64-linux/include/crt/host_config.h:138:2: error: #error -- unsupported GNU version! gcc versions later than 8 are
not supported!
That should have been prevented with the conflicts statement in the cuda build system.
conflicts('%gcc@8:', when='+cuda ^[email protected]' + arch_platform)
where arch_platform = ' arch=x86_64 platform=linux'.
It would also seem that cuda itself should not install with a gcc > 8 as well.
