It's still broken in master.

Easy way to reproduce this is:
OE qemux86@ ~/build/oe-core $ for i in `seq -w 1 100`; do bitbake -c cleansstate perf; bitbake -c build perf | tee log.perf.$i; done

On slow machine I got first failure on 60th iteration, on
much faster machine I got 4 failures in first 20 iterations.

Can you please fix it properly instead of removing whole ${B}?

do_configure_prepend () {
    # Fix for rebuilding
    rm -rf ${B}/
    mkdir ${B}/
...

I wish there is easier way to undo this commit in .bbappend, we very
rarely rebuild perf in the same build directory, but too often we see
normal clean builds failing in perf do_configure or do_populate_lic tasks :/.

Regards and thanks for feedback (it's broken for 8 months and no reply
after it was reported 3 months ago).
