 Using rtems-tools 4.11 and enabling the trace buffer generator, I'm
 getting errors like this:

 These errors are probably not present in the rtems-tools master branch (I
 know that using rtems-tools master on rtems 4.11 has worked previously).

 I'm guessing that this could either be fixed by adding something like
 {{{
 header = '#include <rtems/score/percpu.h>'
 }}}
 in rtld-trace-buffer.ini

 or by backporting the following change from the rtems-tools master branch
 to 4.11:
 https://git.rtems.org/rtems-tools/commit/linkers/rtld-trace-
 buffer.ini?id=f11d18b9b1f438b2dc83b92e39d945d5ac654bbd
 which seems to have the necessary includes in place.
