Well, those options will give you NetBSD/current not a "netbsd-5" source tree.
Please try this:

cd src
cvs -d anoncvs%anoncvs.NetBSD.org@localhost:/cvsroot -A -P -d -rnetbsd-5

That works for me. Have you tried to remove your object and destination 
directory?

That's not necessary, unprivileged builds work fine.

That's clearly not a good idea.

Please get rid of all of those. NetBSD's build system uses appropriate 
optimisation
for the build. And they differ for parts of the source tree. Blindly overriding
the like this is a bad idea.

You could use install "pkgsrc/devel/cpuflags" and use this ...

CPU_FLAGS= -march=pentium-m
.sinclude "/usr/pkg/share/mk/cpuflags.mk"

... but I seriously doubt that there will be any measurable performance gains.

        Kind regards
