trace: rerun tracetool after ./configure changes
Autogenerated code in trace.h/trace.c and friends is specific to the
config-host.mak TRACE_BACKENDS setting and must be regenerated when
./configure --enable-trace-backend= changes settings.
This patch ensures that changes to TRACE_BACKENDS are detected. For
example, the trace-root.h file is now updated after switching trace
backends:
$ ./configure && make
$ cp trace-root.h /tmp/old-trace-root.h
$ ./configure --enable-trace-backend=simple && make
$ diff -u /tmp/old-trace-root.h trace-root.h
