debian/arm or debian/armel ? Which specific binaries?

oldabi syscalls.

Because the error is being printed from a place than usual. Qemu appears
to think the binary is eabi and is thus not reducing 0x900000 as usual
when running oldabi binaries.

The warned syscalls (setxattr, getattr) go usually via the
unimplemented_nowarn path, so no warning should be visible for users.
