[PATCH] rtems-gdb-9.1-1.cfg: Add patch for Cygwin

[Joel Sherrill]

The patch is needed to address link failures introduced when
Cygwin apparently changed their base address for executables.
This is not an issue with gdb 10 and this is a minimalistic
approach to addressing this failure on the 5 branch.

Closes #4523.
