classes/externalsrc: create symlinks for workdir and logs
Auto-create symlinks in the source directory to the work directory (${WORKDIR}) and logs directory (${T}) so that they are easier for the user to find. This is particularly useful within the extensible SDK where the user is less likely to be familiar enough with the structure of the build system to know where to find these things, but otherwise they are a useful shortcut for anyone. (From OE-Core rev: 58adb3904c18acefd0da319e32f66ebca72eeaac) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
