[Buildroot] [git commit] arch/arch.mk: fix check-package warnings

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=e2b07057436fd6e8e7a0c9e2a45cfea193728985
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

"make check-package" is not happy with the formatting of the recently
introduced arch.mk:

arch/arch.mk:1: should be 80 hashes (http://nightly.buildroot.org/#writing-rules-mk)
arch/arch.mk:2: should be 1 hash (http://nightly.buildroot.org/#writing-rules-mk)
arch/arch.mk:4: should be 1 hash (http://nightly.buildroot.org/#writing-rules-mk)
arch/arch.mk:5: should be 80 hashes (http://nightly.buildroot.org/#writing-rules-mk)
arch/arch.mk:6: should be a blank line (http://nightly.buildroot.org/#writing-rules-mk)

Let's fix this by adding a comment header that makes check-package
happy.
