In DRIVER_DEFINES:

DRIVER_DEFINES = \
  -DSTANDARD_STARTFILE_PREFIX=\"$(libdir)/\" \
  -DSTANDARD_EXEC_PREFIX=\"$(libdir)/gcc-lib/\" \
  -DDEFAULT_TARGET_VERSION=\"$(version)\" \
  -DDEFAULT_TARGET_MACHINE=\"$(target_alias)\" \
  -DTOOLDIR_BASE_PREFIX=\"$(exec_prefix)/\"


The 'set-to-0' thing is historical, it's only used in the protoize
testing when it doesn't really matter what the variables are defined
to---tmp-proto.c needs them defined, and they have to be inside a
single shell argument, so they shouldn't contain quotes :-(.
