the differences don't affect the actual compilation.
newlib/configure.ac uses AC_CONFIG_FILES to hack up Makefile. multi.m4
uses AC_OUTPUT_COMMANDS instead.
newlib/configure.ac passes LDFLAGS to init-cmds while multi.m4 does not
(it does pass additional non-C toolchain vars that newlib doesn't use).
afaict omitting LDFLAGS shouldn't make a diff since newlib has been
clobbering that with an invalid setting ($ldflags).
there's also a few internal variable names that changed, but since newlib
doesn't check them, it shouldn't matter.

yes, i've build every commit against bfin-elf multilib. if you want me
to check something specifically, please highlight it.
