    cmd/link: use current GOROOT for source file paths for standard library · 83746fd5
    Russ Cox authored
    This CL changes the source file information in the
    standard library's .a files to say "$GOROOT/src/runtime/chan.go"
    (with a literal "$GOROOT") instead of spelling out the actual directory.
    The linker then substitutes the actual $GOROOT (or $GOROOT_FINAL)
    as appropriate.
    
    If people download a binary distribution to an alternate location,
    following the instructions at https://golang.org/doc/install#install,
    the code before this CL would end up with source paths pointing to
    /usr/local/go no matter where the actual sources were.
    Now the source paths for built binaries will point to the actual sources
    (hopefully).
    
    The source line information in distributed binaries is not affected:
    those will still say /usr/local/go. But binaries people build themselves
    (their own programs, not the go distribution programs) will be correct.
    
    Fixing this path also fixes the lookup of the runtime-gdb.py file.
    
    Fixes #5533.
