ld: Support ELF GNU program properties
From .note.gnu.property section in each ELF input, we build a list of GNU properties if .note.gnu.property section isn't corrupt. The unknown properties are ignored. All property lists in relocatable inputs are merged into an output property list. When -z stack-size=N is used and N isn't 0, the GNU_PROPERTY_STACK_SIZE property will be merged with or added to the output property list. .note.gnu.property section is generated in output from the output property list. bfd/ * Makefile.am (BFD32_BACKENDS): Add elf-properties.lo.
