BuildStream attempts to create very long filenames after finisihing a build

Summary

When building specific projects, apparently only on debian, BuildStream fails consistently with "File name too long" when attempting to recursively symlink debug files.

The symlink will point to a file in /lib/debug/tools/, but the debug base path is repeated (i.e. /lib/debug/tools/lib/debug/tools/lib/debug/tools/.../libcc1.so.0.0.0.

Steps to reproduce

No steps yet, but has been reproduced by two users. Notable similarities were the use of debian (switching to ubuntu apparently solved the issue), building a stage1 gnu toolchain and the fact that both failed to create a symlink to the same debug files.

What is the current bug behavior?

BuildStream fails to build because it seems to create a recursive file path.

What is the expected correct behavior?

BuildStream should not create a recursive file path, and pass the build.
