build: Use $(CCAS) for compiling .S files
We fail to pass to $(AS) all of the different flags that may be required for a given set of CFLAGS. Rather than figuring out the host-specific mapping, it's better to allow the compiler driver to do that. However, simply using $(CC) runs afoul of clang trying to build the option roms. C.f. 3dd46c78525a30e98c68, wherein we changed from using $(CC) to using $(AS) in the first place. Work around this by passing -fno-integrated-as to clang, so that we use the external assembler, and the clang driver still passes along all of the options that the assembler might require.
