The above bit as a script should be run as a script before you just do a 
normal compile/make/make install of a source tree.

when you build an srpm with:
rpm --rebuild --target="athlon-pc-linux-gnu" kdelibs.src.rpm
You should run the above script before this as well. If you do not set the 
target value it will use your system hosttype which is 386, on a normal 
compile like the top those flags will/should overide hosttype and if you can 
see the words:  -O2 -march=athlon you know it is compiling as an athlon 
binary. The same with the SRPM if you dont see that line then it aint 
optimising it.
These things are dependent on the scripts inside the tar files though and 
some were written before athlon was available and only allow iX86 numbers, 
otherwise they get confused and the script crashes. Still you can get around 
them by setting the target as i686-blah-blah (dep on your distro) for SRPMS 
or setting the host to i686 in normal source compiles in the configure script 
but if you export the above flags beforehand it should still compile as 
athlon as you will see if you watch for the words.

Of course for SRPMS the RPMs you build will have athlon in the name so if 
your HOSTTYPE=i386 then rpm will give a 'wrong architecture' error when 
installing so you install with rpm --ignorearch and --ignoreos (if necessary)

Also with the SRPMS sometimes they have a dep that is on your system but not 
as an rpm, you can use --nodeps sometimes when building them and it will at 
least build the source so you can install it but it may not build srpm/rpm 
like that.
