The use of -mlong-calls was removed in r358851 for LLVM 10.0, leaving STATIC_CFLAGS empty.

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.

Tested on real hardware, and in cross-compile environment.

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.

This allows us to have binaries larger than the 32MiB limit of a branch instruction. The main use of this is with clang. Clang 3.8.0 has been shown to be larger than the above limit.
