Subject: [PATCH] Use the multilib config files from ${B} instead of using the
 ones from ${S}

Use the multilib config files from ${B} instead of using the ones from ${S}
so that the source can be shared between gcc-cross-initial,
gcc-cross-intermediate, gcc-cross, gcc-runtime, and also the sdk build.
