configure: Fix ppc container_cross_cc substitution

When moving this code out of probe_target_compiler(), we failed to adjust
the variable in which the target is located, resulting in e.g.
powerpc64-linux-user-linux-gnu-gcc-10

Fixes: cd362defbbd ("tests/tcg: merge configure.sh back into main configure script")
