Make failing

[Phil Holmes]

On my build Ubuntu machine, make is currently failing with the following 
output:

/home/phil/lilypond-git/lily/score-engraver.cc: In member function 'virtual 
void Score_engraver::announce_grob(Grob_info)':
/home/phil/lilypond-git/lily/score-engraver.cc:164: error: 
'VALGRIND_PRINTF_BACKTRACE' was not declared in this scope
make[1]: *** [out/score-engraver.o] Error 1
make[1]: Leaving directory 
`/media/IntelSSD/lilypond/lilypond-git/build/lily'
make: *** [all] Error 2

This looks like a problem with Mike's latest patch - I assume it requires 
valgrind to be present on the build machine, and it's not on mine.  Debug 
code?

+    {if (info.grob ()->name () == "StemStub") VALGRIND_PRINTF_BACKTRACE 
("foo");
