Omit path to lld binary from lld's error, warning, and log output. lld currently prepends the absolute path to itself to every diagnostic it emits. This path can be longer than the diagnostic, and makes the actual error message hard to read. There isn't a good reason for printing this path: if you want to know which lld you're running, pass -v to clang – chances are that if you're unsure of this, you're not only unsure when it errors out. Some people want an indication that the diagnostic is from the linker though, so instead print just the basename of the linker's path.
