[PATCH] configure: pass correct cflags to container-based cross compilers

[Paolo Bonzini]

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.
