[Buildroot] [PATCH 7/7 v2] package/uclibc: check for config file

[Yann E. MORIN]

Add a check (before we call kconfig-package) that ensures the user has
set a kconfig-file.

Signed-off-by: "Yann E. MORIN" <yann.morin.1998 at free.fr>

Changes v1 -> v2:
  - use BR_BUILDING in its own ifeq, do not coalesce with the existing
    ifeq
  - fix commit log  (Baruch)
