rpm build issues

[Xavier Toth]

I downloaded the rawhide kernel sources and tried to make a i686 rpm.
Following the instructions on
http://fedora.redhat.com/docs/release-notes/fc6test2/  I ran 'rpmbuild
-bp --target i686 kernel-2.6.spec' then copied
configs/kernel-2.6.17-i686.config to .config and edited the Makefile
changing EXTRAVERSION = -prep to EXTRAVERSION = -1.2647.fc6. I then
did a 'make oldconfig' (unclear why this is necessary since the copied
a prebuilt config file already) and then 'make rpm'. The result of the
make is rpmbuild/RPMS/i386/kernel-2.6.171.2647.fc6-1.i386.rpm and
there are several issues with this:
1) a i386 rpm was produced not a i686 rpm
2) the EXTRAVERSION losses its '-' and so is run up against the kernel
version in the file name '2.6.171.2647.fc6'

Are the instruction correct? Are these bugs in the build system?
