Tools debug builds are built with optimization level -O1, inherited from
the CFLAGS definition in StdGNU.mk. Optimizations confuse the debugger,
and the comment justifying -O1 in StdGNU.mk should not apply for a
userspace library. Disable optimization by appending -O0 to CFLAGS,
which overrides the -O1 flag specified earlier.
Also specify -g3, to add macro debugging information which allows
gdb to expand macro invocations. This is useful as libxl uses many
non-trivial macros.
