You are putting a lot of burden on people doing test builds.
You _can_ avoid it by seeding those configurations. You place the options you want to force to a specific value in a file, and then do:
make allmodconfig KCONFIG_ALLCONFIG=seed-config-file
So, to turn off samples:
CONFIG_SAMPLES=n
in seed-config-file. Hence, you can still do an allmodconfig build but without building the samples subdir.
