Cannot build evbarm-current with Clang

[Adam <adam%netbsd.org@localhost>]

Greetings,

My current build of evbarm (MACHINE_ARCH=earmv7hf) fails with:

[...]
'arm7m' is not a recognized processor for this target (ignoring processor)
[...]
/dist/src/sys/arch/acorn32/stand/lib/riscoscalls.S:360:2: warning: use of SP or PC in the list is deprecated
 stmfd sp!, {r4, fp, ip, lr, pc}

/dist/src/sys/arch/acorn32/stand/lib/riscoscalls.S:366:2: error: invalid instruction, did you mean: ldmdb?

/dist/src/sys/arch/acorn32/stand/lib/riscoscalls.S:372:2: warning: use of SP in the list is deprecated

I am using Clang (HAVE_LLVM=yes).

I was able to build this architecture around April this year. Has something changed since then? Can somebody build it with Clang?

Kind regards,
Adam
