Andrew Turner 522126fea7 csu: Teach csu about PAC and BTI ... Add the Branch Target Identification (BTI) note to libc assembly sources and Pointer Authentication Code (PAC) instructions to _init and _fini. _init and _fini may be called indirectly so need a BTI landing pad. As they are non-leaf functions use the appropriate PAC instruction that also guards against changing the link register. As all object files need the note for any binary using these object files we need to insert it in all asm files.
