[Buildroot] [PATCH] buildroot: Makefile: Allow target board makefile fill in default target_skeleton path.

[Sonic Zhang]

From: Sonic Zhang <sonic.zhang at analog.com>

If the target skeleton path is empty in config, don't change variable
TARGET_SKELETON in buildroot Makefile. Allow the target board makefile
fill in a default path.
