When the path to a br2-external tree is relative, make enters an endless
recursive loop (paths elided for brevity):
$ make BR2_EXTERNAL=.. foo_defconfig
make[1]: stat: ../configs/../configs/../configs[...]/toto_defconfig: Filename too long
make[1]: *** No rule to make target '../configs/../configs/../configs[...]/toto_defconfig',
needed by '../configs/../configs/../configs[...]/toto_defconfig'. Stop.
Makefile:79: recipe for target '_all' failed
make: *** [_all] Error 2
It is a bit complex to understand the actual technical reason for this
never-ending expansion; it seems it happens in the code generated by the
percent_defconfig macro. Not sure why, though...
But the root cause is the relative path.
Just use absolute, canonical paths to br2-external trees. Always.
