[PATCH] Drop prefix from unsupported source path.

Hi,

Various gdb tests report the absolute path to a source file in an 
UNSUPPORTED outcome.  This creates noise when comparing result output 
with previous test runs.  This patch drops the directory prefix from the 
reported path in a couple of the offending unsupported calls.

OK?

Cheers
