[Buildroot] [git commit] package/pkg-utils: refine KCONFIG_MUNGE_DOT_CONFIG

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=ff506cdeb7d8c7f98164a77b516d1bcc5c2d67f3
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Given a .config with:

    FOO="1234"
    BAR="$(FOO)"

and then:

    $(call KCONFIG_SET_OPT,FOO,azerty)

would yield a .config with just:

    FOO="azerty"

because \<FOO\> would match the assignment to BAR.
