Use the correct instruction to clear the frame pointer.

Since all arm64 assembly code in libc uses the ENTRY* macros from <machine/asm.h> they are already get the necessary "bti c" instructions. Passi the -mmark-bti-property option to mark the corresponding object files as having BTI support.

Populate the non-LOAD openbsd.syscalls section (and PT_OPENBSD_SYSCALL) with {uint offset, uint syscall#} entries in libc & ld.so. In libc a few syscall# entries (break, sigprocmask, _tfork, _threxit) are duplicated because additional or inline uses occur (that situation is handled elsewhere) ok kettenis

Drop __multf3 from the list; it isn't actually exported.
