[oe] Changing recipe files

[Geoffrey Wossum]

Hi all,

I'm working on build gdb-cross for the AVR32.  In the process, I've figured 
out I need to modify the do_stage() function in gdb-cross.inc.  I need to 
touch some files to prevent "oe_runmake install" from wanting to run makeinfo 
(ah, my old nemesis makeinfo) since makeinfo is a native makeinfo is not 
available in the OE build environment.

For whatever reason, though, the system doesn't seem to pick up my change.  
I've tried running "bitbake -c rebuild gdb-cross".  I've tried bumping up the 
PR value in recipe file.  I've tried wiping out the work directory for 
gdb-cross.  Still doesn't want to use my modified version of do_stage().  
Every time I look in the run.do_stage.xxxxx it's the old version of 
do_stage().  I figure I could wipe out my entire build tree and the change 
would be caught, but I don't want to wait 2.5 hours to rebuild everything.  

What is the magic incantation for my change to take effect?

TIA,
