This may work as a workaround but I believe x.py build should not expose DESTDIR to the LLVM build, i.e. it should unset that env var for the relevant commands, which will remove the need to have RUST_DESTDIR at all.
This seems to be a combination of oversight and probably x.py install not being used to also do the build step, most of the time (think make && make DESTDIR=$PKG_OUT_DIR install).

Yes, I think @eddyb is right that the preferred approach would be to unset the env variable when invoking cmake during our LLVM installation/building, since we should be in full control of where LLVM is installed (vs. Rust itself, which I guess makes sense that DESTDIR should affect that). |
When running a command like `DESTDIR=foo x.py install` in a completely clean build directory, this will cause LLVM to be installed into `DESTDIR`, which then causes the build to fail later when it attempts to *use* those LLVM files.
