clang.bbclass,compiler-rt: Do not set -target for native clang

When building native recipes using clang as native compiler e.g.
compiler-rt-native, setting -target can be out of sync with the
underlying distro's understanding of gcc tuple e.g. aarch64-linux
or aarch64-linux-gnu, which is used by distros to house the gcc
runtime e.g. on ubuntu

/usr/lib/gcc/aarch64-linux-gnu/11
/usr/lib/gcc/aarch64-linux-gnu/9

if we provide -target its not able to deduce it from the build host
which is required for native packages

try with
recipe-sysroot-native/usr/bin/clang -xc /dev/null -rtlib=libgcc --unwindlib=libgcc -stdlib=libstdc++ -v

or

recipe-sysroot-native/usr/bin/clang -xc /dev/null -rtlib=libgcc --unwindlib=libgcc -stdlib=libstdc++ -target aarch64-linux -v

to see the difference
