This fixes two issues: If gyp is run with the CXX and CC environment
variables set, it will produce different ninja build files.
sync-and-gyp now tracks the values of those variables; if they change,
re-run gyp.
Secondly, we introduced find.py, which is used inside gyp files. If
the contents of certain directories changes, gyp should be re-run. So
now we track those directories too.

Make the bin/c and bin/ac scripts work with sh. The scripts are run with
/bin/sh shebang, which fails atleast on ubuntu 12.04 /bin/sh. The sh in
Ubuntu 12.04 is dash.
The fixes are according to the suggestions in http://mywiki.wooledge.org/Bashism
Also run "compare" script with explicit ./bin/ path to support people
who do not have skia/bin in PATH.

These are the scripts I've been homegrowing for measuring perf impact. I think we found them useful today as a way of sifting through the noise.
