Subject: 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.  -Erik
