configure: remove --enable-profile

Browse Source 
The --enable-profile switch simply adds -p to the CFLAGS, which enables
gcc's extremely worthless "prof" profiling support. This kind of
profiling is broken on the conceptual level and thus harmful, and even
if you want it, you can enable it manually with --extra-cflags.

Also remove $_march $_mcpu from the CFLAGS code. These variables were
always unset, as the code setting them has been removed earlier.
