rust: Avoid buildtools+uninative issues with glibc symbols mismatches
If we use an external buildtools tarball, that combined with uninative results
in build failures with symbol mismatches. This was tracked down to the prebuilt
rust binaries that are downloaded. The libc/loader used to load them is used to
execute target binaries/libraries and therefore anything with built with a newer
libc would fail.
Add code to use patchelf to change the interpreter to our own uninative one if
present which ensures the newer libc and loader are used, hence avoiding the issue.
