Fix libdwarf include path to fit debian-like systems too. Borislav Petkov reported: > even after installing libdwarf-dev on my debian box here, > make in tools/perf/ still complains that it cannot find libdwarf: > > Makefile:491: No libdwarf.h found or old libdwarf.h found, disables dwarf > support. Please install libdwarf-dev/libdwarf-devel >= 20081231 > > The problem is that the include path on debian is not > /usr/include/libdwarf/ but simply /usr/include because the debian > package libdwarf-dev puts the headers straight into > /usr/include. This patch adds -I/usr/include/libdwarf to BASIC_CFLAGS and fix probe-finder.h to include just libdwarf.h/dwarf.h. This patch also adds a workaround for the undefined _MIPS_SZLONG bug in libdwarf.h.
