Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both a
size and performance penalty to profiling applications this way, as well as
Heisenberg effects, where the act of measuring changes what is measured.
There are better tools for doing profiling, such as OProfile, that do not
require gcc to instrument the application code.
