It would be nice to emit the name of the original files as well, making
debugging issues a bit easier. So maybe buffer objcopy's output and in case of a
message, print the original file name.

Control: reassign -1 binutils

Hi,

That "gibberish" name is an internal name used in objcopy and it makes
more sense to fix this bug at its roots (which would be in objcopy
itself), reassigning accordingly.

Reproducer:

"""
$ cd /tmp
$ cp /bin/ls .
$ objcopy --add-gnu-debuglink /bin/test ls
objcopy: stnJQXz3: debuglink section already exists
"""

The "stnJQXz3" name is indeed not very helpful and should have said "ls"
(or "/tmp/ls" in this case)
