Hi there,
I can't understand why this part of make buildkernel is so long on my
amd64 machine (8.1-R)

This command takes around 5-6 minutes before continuing, on my i386
machine (which is really old) it only takes about 20 seconds. The
kernel configs are almost the same for both machines.
are there any differences in /etc/make.conf?
cheers.

Do you have any idea?

No, except the KERNCONF entry it's exactly the same :
hmmm....strange. could you post the ouput of `make -VCFLAGS -VCOPTFLAGS` on
both your machines, please?
cheers.

I think the problem is the amd64 architecture. When I buildkernel
using TARGET_ARCH=i386 it takes only one minute or even less, it's
only native target (amd64) which is long.
i finally had the time to measue target buildkernel for amd64 and for i386:
make buildkernel KERNCONF=GENERIC TARGET=i386 248,84s user 47,29s system 101% cpu 4:52,15 total
vs.
make buildkernel KERNCONF=GENERIC TARGET=amd64 246,36s user 47,08s system 103% cpu 4:44,62 total
...so no difference in my case. this was tested on a very recent HEAD with arch=amd64.
cheers.
