libdebugger build error on atsamv

[Joel Sherrill]

This was caught in a build sweep using rtems-bsp-builder.

Configure command:

/home/joel/rtems-cron-5/rtems/configure --target=arm-rtems5 --enable-rtemsbsp=atsamv --prefix=/home/joel/rtems-cron-5/tools/5/bsps --enable-rtems-debug --disable-smp

Compiler output:

This has been fixed. See the simpler beaglebone error, I think number 10. I think your source tree is not up to date in your build system.
