No, Buildroot is not smart enough to do this, but it's not a problem.
The relocate-sdk.sh is necessary to fixup path in .la files, -config
scripts and stuff like that, which you don't have in a SDK that is just
a pure toolchain. The only thing that really matters is to have
relative RPATH, and that's already done as part of the "make sdk"
Hence, "make sdk" + tarballing output/host already makes a toolchain
that is relocatable, and usable as-is as an external toolchain for
another Buildroot build.
