[Buildroot] [PATCH v3 3/6] Makefile: Generate %_defconfig recipes from macro.

From: Patrick Williams <patrick at stwcx.xyz>

To reduce duplication in the %_defconfig recipes with $(TOPDIR) and
$(BR2_EXTERNAL) versions, generate these from a macro.  The macro is
now called on a list of directories containing the appropriate ones.
