The current checkstack.pl script has a few problems, stemming from the overly simplistic attempt at parsing objdump output with regular expresions. Since gcc 4.6 introduced the -fstack-usage option, we can now get the exact stack use instead of resorting to ad hoc methods. This introduces two small scripts. One for running make with KCFLAGS set to -fstack-usage, followed by collecting the generated .su files in a single output file. Another for taking two such output files and computing the changes in stack use. 2/4 and 3/4 may be too small by themselves; they can easily be squashed into 1/4. v2: Use KCFLAGS instead of EXTRA_CFLAGS. A few more details in commit messages. Simpler option handling in stackusage. Removed accidental leftover debug prints.
