[Buildroot] [git commit] manual: switch BR2_EXTERNAL examples to use absolute paths

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=1de64ec8c08f6e954f1f1b616ebb3be7f9cef3e7
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Although it is possible to use relative paths, there are a few pitfalls
when doing so.

To avoid confusion for a (newcoming) user, use absolute paths in the
manual (as is done in examples for $(O)), since it is guaranteed to be
working without corner cases.

[Peter: s/relatively/relative/ as suggested by Thomas]
