Yes, that is a great ides, maybe a choice like:

    choice
        bool "Single-binary mode"
        default BR2_PKG_COREUTILS_SINGLE_SYMLINKS

    config BR2_PKG_COREUTILS_SINGLE_NONE
        bool "none"

    config BR2_PKG_COREUTILS_SINGLE_SYMLINKS
        bool "symlinks"

    config BR2_PKG_COREUTILS_SINGLE_SHEBANGS
        bool "shebangs"

    endchoice

And the corresponding code in the .mk file, of course.

Yann E. MORIN.
