Example Makefile project showing error on relocated sources

When an elf file is compiled with relative paths (e.g. ../src/main.c) and the file is relocated, source lookups created with the 
CSourceNotFoundEditor cause breakpoints not to be insertable.

Please see the attached project for a test case.

Steps to reproduce:
- Build attached project
- Debug relative_oldsrc.elf
- When stopped at main, in the CSourceNotFoundEditor, locate the file
  - this creates a new mapping, and reloads the correct file in the editor)
  - GDB reports the file as fullname="/scratch/RelocatingProject/Debug/../oldsrc/main.c"
  - the file to browse to is /scratch/RelocatingProject/src/main.c
- Insert a breakpoint on main.c:5

In the GDB console you will have an error similar to:
No source file named /scratch/RelocatingProject/oldsrc/main.c.

In the GDB traces you have this:
790,985 33-break-insert -f /scratch/RelocatingProject/oldsrc/main.c:5
790,994 &"No source file named /scratch/RelocatingProject/oldsrc/main.c.\n"

"/scratch/RelocatingProject/oldsrc/main.c:5",times="0",original-location="/sc\
ratch/RelocatingProject/oldsrc/main.c:5"}
