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.
