Yes, just add SHF_AARCH64_PURECODE here, which demonstrates that the arch-specific flag is actually parsed for all targets.

Arguably the test is not perfect: we don't test that the flag value is expected, but for the purpose of ensuring that this flag is parsed, this test is ok.

(Right that many generic flags are not tested, but they are usually never used in linker scripts)
