[Bug gcov-profile/44728] New: gcov chokes when "." is present in DIR argument to -o flag

["ajshower at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When trying to specify a directory that contains a "." for gcov to look in for
output files, gcov does not act as expected.

Example:
/home/test$ gcc-4.3 main.c -fprofile-arcs -ftest-coverage
/home/test$ ./a.out
/home/test$ gcov-4.3 -o/home/test/ main
  <expected output>
/home/test$ mkdir 1.1; cp main.c 1.1; cd 1.1

/home/test/1.1$ gcc-4.3 main.c -fprofile-arcs -ftest-coverage
/home/test/1.1$ ./a.out
/home/test/1.1$ gcov-4.3 -o/home/test/1.1/ main
  /home/test/1.gcno:cannot open graph file

I'm guessing that gcov is mistaking the DIR argument for the FILE argument to
the -o flag.

gcov-4.3 --help
    -o, --object-directory DIR|FILE Search for object files in DIR or called
FILE
