Comment (by criezy):

 I am not sure adding gprof instrumentation to the builds on buildbot is a
 good idea as:
 - The instrumention overhead can be quite high, degrading performances for
 all users of those builds, even though most of those users don't care or
 want gprof data.
 - The buildbot builds are compiled without optimizations, which is not
 ideal for profiling since it could highlight performance issues in code
 that is actually optimized by the compiler in release builds. So usually
 you want to profile executables that have been built with optimizations.

 Can you not build scummvm yourself?

 There may also be some better alternatives to gprof that may not require
 instrumentation at compile time. On Linux I usually use the
 valgrind/callgrind/kcachegrind combo for profiling, and as far as I know
 there is also a profiler in Visual Studio. But I am not sure what exists
 for minggw builds on Windows.
