[PATCH 11/10] arm64: unbreak DYNAMIC_DEBUG=y build with clang

Current versions of clang does not like the %c modifier in inline
assembly for targets other than x86, so any DYNAMIC_DEBUG=y build
fails on arm64. A fix is likely to land in 9.0 (see
https://github.com/ClangBuiltLinux/linux/issues/456), but unbreak the
build for older versions.

Fixes: arm64: select DYNAMIC_DEBUG_RELATIVE_POINTERS
