[ELF] Place .note in the first page to ensure they are available in core files Summary: Other large sections (e.g. .rela.dyn .dynstr) may push .note.* off the first page. They won't be available in core files if RLIMIT_CORE is limited. This patch gives priority to alloctable SHT_NOTE sections so that they are assuredly in the first page and will be available in core files. They are small and contain important information (e.g. .note.gnu.build-id identifies the origin of the core, .note.tag stores NT_FREEBSD_ABI_TAG). Note: gold Output_section_order has a similar rule: // Loadable read-only note sections come next so that the PT_NOTE // segment is on the first page of the executable.
