geninfo: fix parsing of gcc 4.7 gcov format

GCC 4.7 changes the gcov format for lines which can only be reached
by exceptions to "=====" instead of "#####". This results in the
following warning:

geninfo: Argument "=====" isn't numeric in numeric gt (>) at geninfo
line 1281.

Fix this by handling "=====" correctly.
