For nativesdk, symlinks created by do_install contain ${SDKPATHNATIVE}.
This is a problem with SDKs that include nativesdk-binutils and nativesdk-gcc.
When extracting such an SDK dangling symlinks are created, because
relocate_sdk.py does not adjust symlinks. As a result gcc ends up calling the
host binutils.
Use the os.path.relpath function to obtain shorter relative paths, which do not
contain ${SDKPATHNATIVE}.
