I've just pushed the following.

I expect the actual problem is that the buildsystem is recusing into
this directory twice simultaneously for "all" and "install" at the same
time. That seems likely to be an issue with the Makefile in the parent
directory.

Should subdirs-install depend on subdirs-all perhaps?

    Revert "tools/hotplug: fix race during xen.conf creation"
    
    This reverts commit eac3f5122fd4769b2885d8ad78bcbcf5df2472c1.
    
    The "all" target should never depend on "install", it is supposed to only build
    not install.
