I've looked at this and split this part in a separate patch, and applied
it locally, please take a look, now looking at the other bit of the
patch.

commit 1b59e3b7bfc6183d3dc9f119e1875f9607d29d96

    perf trace: Fix the selection for architectures to generate the errno name tables
    
    Make the architecture test directory agree with the code comment.
    
    Committer notes:
    
    This was split from a larger patch.
    
    The code was assuming the developer always worked from tools/perf/, so make sure we
    do the test -d having $toolsdir/perf/arch/$arch, to match the intent expressed in the comment,
    just above that loop.
