Set or show the option 'exec-file-mismatch'. When GDB attaches to
a running process and can determine the name of the executable file
the process runs, this new option indicates whether to detect mismatch
between the name of the current executable file loaded by GDB
and the name of the executable file used to start the process.
If 'ask', the default, display a warning and ask the user
whether to load the process executable file; if 'warn', just display
a warning; if 'off', don't attempt to detect a mismatch.

If the debugger can determine the name of the executable file running
in the process it is attaching to, and this file name does not match
the name of the current exec-file loaded by @value{GDBN}, the option
@code{exec-file-mismatch} specifies how to handle the mismatch.
