This test passes as-is on non-X86 hosts only because almost no target
implements `isValidFeatureName` (the default implementation
unconditionally returns true). RISC-V does implement it, and like X86
checks that the feature name is one supported by the architecture. This
means the test creates an additional warning on RISC-V due to
`_attribute__((target("avx512f")))`.
The simple solution here is to just explicitly target x86_64-linux-gnu.
