(note: the `GNU_PROPERTY_X86_ISA_1_{NEEDED,USED}` values changed.
D98817 <https://reviews.llvm.org/D98817> has removed support for the old values.)

GCC 11 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250)
`-march=x86-64-v[234]` produced object files have such notes to indicate the
micro-architecture ISA levels.
