Issue 2513: Build: add -fno-tree-vrp to CXXFLAGS for gcc 4.7.0

That optimization breaks min() call in simultaneous-music-iterator.cc
leading to incorrect output and bogus barcheck errors.

Generalize STEPMAKE_GXXCODEGENBUG to show bug description with the flag.

GCC bug reported:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53239
