I forgot to mention last time, I hit this:

  meson.build:79:11: ERROR: Unknown variable "conf10".

But I added this:

diff --git a/meson.build b/meson.build
index 31f8a101190e..9c800b80d341 100644
--- a/meson.build
+++ b/meson.build
@@ -23,6 +23,7 @@ mandir    = join_paths(prefixdir, get_option('mandir'))
 htmldir   = join_paths(prefixdir, get_option('htmldir'))
 
 conf = configuration_data()
+conf10 = configuration_data()
 
 libtraceevent_dep = dependency('libtraceevent', version: '>= 1.5.0', required: true)
 libtracefs_dep = dependency('libtracefs', version: '>= 1.6.0', required: true)

As a work around. But now I get this:

../tracecmd/trace-profile.c:13:10: fatal error: libaudit.h: No such file or directory
   13 | #include <libaudit.h>
      |          ^~~~~~~~~~~~


We're missing the -DNO_AUDIT added when not there, as that file has:

#ifndef NO_AUDIT
#include <libaudit.h>
#endif
