Sure.

I don't.  That's supposed to disable automatic profiling and compiling
with -pg, not the manual profiling commands.

You don't need this, by the way.  Unlike the gdb subdirectory, the
gdb/gdbserver subdirectory is standalone.  You need the whole source

should be in the manual, or at least the README.
