[poky] [PATCH] externalsrc: Change absolute symlinks to relative ones

[Erdmann, Jens]

Hi Paul,

Thanks for your reply. The problem occured after altering custom recipes with
devtool. We worked on a native and on a nonnative recipe and got following
messages:

NOTE: api-gen-native: compiling from external source tree /home/erdmann/yocto/build/workspace/sources/api-gen-native

Please replace this with a relative link.

I tried to double check and am quite conviced we did not try to install these
symlinks. I hope these informations draw a more clear picture of the
problem which lead to this attempt to fix this.

Regards,

Jens Erdmann
