Log Message:
geninfo: fix processing of pre-3.3 gcov files
When trying to collect coverage data for programs compiled with
GCC versions prior to 3.3, geninfo skips each data file with the
following warning:
geninfo: WARNING: cannot find an entry for test.c.gcov in .bb file,
skipping file!
Fix this by deriving the source code filename from the gcov filename
in case the gcov files do not follow the GCC 3.3 format.
