Previously, sed was used on the generated assembly to rewrite the section type. Instead, write the notes in assembly which permits setting the correct section type directly. While here, move inline assembly entry points out of C and into assembly for aarch64, arm, and riscv.

Rename the one dummy asm file we have to a '.S' to force the implicit rules to build with the compiler rather than the assembler.

On powerpc64 this is an empty file, but on powerpc and powerpcspe this does contain some save/restore functions, which may not actually be necessary for newer modern GCC and clang. This appeases the in-tree gcc, though, and is needed in order to switch to the BSD CRTRBEGIN.

As the final step, the C compiler generates an object file from the modified assembly output. Currently this last step uses $CC with only $ACFLAGS. However, for other uses in the tree, $ACFLAGS is meant to include assembly-specific compiler flags that are in addition to $CFLAGS (see default .S.o rules bsd.suffixes.mk). In particular, external toolchains may require additional flags to select a non-default target which will be present in CFLAGS but not ACFLAGS. To support this while still mitigating the issue with CFLAGS described in r234502, include a modified CFLAGS that excludes "-g" when assembling the modified assembly files. Note that normally an assembler ($AS) is used to assemble .s flags to object files (see bsd.suffixes.mk). However, llvm-based toolchains do not currently have a stand-alone assembler.
