Under POSIX behavior of leading // is implementation defined. Musl does preserve it in realpath, glibc does not. That means the test was failing when executed on alpine linux. Original issue #508 was about // in the path, not about leading ones. When executed in such environment, the test will still test what it should when the explicit mangling of the path is not done. Fixes #5652 https://github.com/rubygems/rubygems/commit/0fa7373bf6
