archiver: create dir 'B' explicitly while WORKDIR changed
In the do_unpack_and_patch task of archiver, the changed 'WORKDIR' also
casued 'B' changed, create dir 'B' for the possibly requiring of the
tasks which executed in do_unpack_and_patch task.
Such as cut-ecgl's do_patch required 'B' existed:
...
| cp: target 'tmp/work/x86_64-wrs-linux/cut-ecgl/1.0-r0/archiver-work
/cut-ecgl-1.0' is not a directory
...
| ERROR: Function failed: do_patch (log file is located at tmp/work/
x86_64-wrs-linux/cut-ecgl/1.0-r0/temp/do_unpack_and_patch/
log.do_unpack_and_patch.11886)
...
The 'B' dir is implicitly created at the task executing time while the
task tag 'dirs' is not assigned. In the above cut-ecgl example, the 'B'
was created at the wrl_buildlink executing time which is the prefuncs of
task do_unpack. So the following do_patch could use 'B' correctly. But
wrl_buildlink is unnecessary and not invoked in the do_unpack_and_patch
task.
