I am trying to build with a kernel older than 4.1, and get the following error:

error: 'struct perf_event_mmap_page' has no member named 'aux_size'
  148 |   return m_mmap_meta->aux_size;

aux_size was added in Linux 4.1.  It appears the Intel PT plugin was added in
LLVM 13, I can currently build LLVM 12 and hope to be able to upgrade to 13
when it's released.
