You may want to try,

As that will print the full assembler command line, among other things.
E.g.
...
/usr/libexec/gcc/m68k-unknown-linux-musl/as -v -mcpu=68020 --pcrel -o a.o a.s
Thanks, so it fails when -mcpu=68040 is passed to the assembler.
Oh, I misread "caar" as "cacr". The latter exists on MC68040, the
former does not. However, that doesn't explain the failures for pflusha,
which is supported on 68040.
After disabling CONFIG_680[236]0 in the kernel config, I can build
it fine using the buildroot toolchain.
Conclusion: make sure your toolchain supports (a superset of) the
CPUs supported by your kernel config.
