On most architectures crt objects are compiled in a multiple-step process so that sed can be run on the generated assembly. 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.
