[Buildroot] Excluding certain architectures for a package

[Yann E. MORIN]

Danillo, All,

You can add a dependency on architectures like any other dependency; see
the manual:
    https://buildroot.org/downloads/manual/manual.html#dependencies-target-toolchain-options

Quoting:

    * Target architecture
      - Dependency symbol: BR2_powerpc, BR2_mips, … (see arch/Config.in)
      - Comment string: no comment to be added 

For example, to exclude all of mips and mips64:

    # Crypto opt not available for mips:
    depends on !(BR2_mips || BR2_mipsel || BR2_mips64 || BR2_mips64el)

Adapt appropriately, of course.

Regards,
Yann E. MORIN.
