[AsmPrinter] __patchable_function_entries: Set SHF_LINK_ORDER for binutils 2.36 and above

This matches GCC behavior when the configure-time binutils is new. GNU ld<2.36
did not support mixed SHF_LINK_ORDER and non-SHF_LINK_ORDER sections in an
output section, so we conservatively disable SHF_LINK_ORDER for <2.36.
