[Bug 1173562] [NEW] gdb resolves symbolic links for executables in argv[0]

[David Kastrup]

Public bug reported:

Calling gdb on an executable that is a symbolic link will pass the
target of the symbolic link rather than the specified link as argv[0] to
the program.

As a result, if the program relies on the contents of argv[0] (for
example, for figuring out paths relative to the executable or making
decisions based on the name the executable has been called under),
debugging fails.

This seems to be a problem newly introduced in Raring.
