The PT_GNU_PROPERTY is generated by a linker to describe the .note.gnu.property section. The Linux kernel uses this program header to locate the .note.gnu.property section. It is described in "The Linux gABI extension" Include support for llvm-readelf, llvm-readobj and the yaml reader and writers. Differential Revision: https://reviews.llvm.org/D70959
