probe_target_compiler returns nonempty $target_cc for installed toolchains
and $container_cross_cc for container-based toolchains. In both cases
however the flags (coming from $cross_cc_cflags_${target_arch}) must be
in $target_cflags.
Therefore, do not clear them prior to returning from probe_target_compiler.
