Subject: [PATCH 8/9] create-diff-object: ignore .note.gnu.property section
Linux GABI introduced new .note.gnu.property section which contains a program
property note which describes special handling requirements for linker and run-time loader.
Linux GABI specifies 2 types of entries:
GNU_PROPERTY_STACK_SIZE and GNU_PROPERTY_NO_COPY_ON_PROTECTED
These entries should not take effect when using live-patching, thus, ignore the change of
this section
