ELF program properties will be needed for detecting whether to
enable optional architecture or ABI features for a new ELF process.
The PT_GNU_PROPERTY is generated by a linker to describe the
.note.gnu.property section. The definition of PT_GNU_PROPERTY can
be found in [1].
For AArch64, GNU_PROPERTY_AARCH64_FEATURE_1_AND program property type
describes a set of processor features with which an ELF object or
executable image is compatible, but does not require in order to
execute correctly. These processor features are BTI and PAC.
