clang: Change LLVM_TARGETS_TO_BUILD to build everything by default

As described in issue #33, LLVM_TARGETS_TO_BUILD should include
build host as well as target arches and that fails since we build
clang-native once for all due to its inherent cross compilable nature
if one needs to limit the targets please set it in local.conf or
via a bbappend in own layer e.g.

LLVM_TARGETS_TO_BUILD = "ARM"

if you only need 32bit arm or

LLVM_TARGETS_TO_BUILD = "ARM;Aarch64"

in case of both arm 32bit and 64bit

fixes #33
