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.
