Makefile: internally use absolute paths to BR2_EXTERNAL
Using a relative path for BR2_EXTERNAL, and using an external defconfig,
such as in (from a Buildroot top-dir):
make O=.. BR2_EXTERNAL=.. foo_defconfig
is broken. It is unclear why the %_defconfig rule recurses in that case.
This patch internaly makes BR2_EXTERNAL canonical (ie. makes it an absolute
path), and checks the directory exists.
