It seems that we have some kind of a symbol name conflict which causes
CONFIG_SECCOMP to always be read as y.
Unfortunatelly, I could not figure out what is causing this, but simply
renaming SECCOMP to USE_SECCOMP seems to properly work and leaves the
symbol unset unless arch dependencies are satisfied.
This fixes qoriq and others that dont support seccomp from failing due
to procd-seccomp package being selected to get included but it cannot be
built for them:
ERROR: unable to select packages:
procd-seccomp (no such package):
required by: base-files-1637~52b6c92479[procd-seccomp]
Fixes: 4c65359af4 ("build: fix including busybox, procd and apk/opkg in imagebuilder")
