Newlib 2.1.0 not building

[Legimet]

Hi, I think I found a bug in Newlib 2.1.0. I tried building with the following:
./configure --target=arm-none-eabi --prefix=/usr/local
--enable-interwork --enable-multilib --with-gnu-as --with-gnu-ld
--disable-nls --with-float=soft --disable-werror

But when make enters arm-none-eabi/thumb/libgloss/arm/cpu-init, the
build fails with the message
*** No rule to make target
`../../../.././libgloss/arm/../config/default.mh', needed by
`Makefile'.  Stop.
