I apologize for the updates, but I've just repeated that build with
different results. Only the error in gets.c is reported.

../../source/newlib-3.0.0/configure --target=arm-none-eabi
--host=x86_64-pc-linux-gnu --prefix=`realpath ../../prefix`
--docdir=`realpath ../../prefix/share/doc`

I had a similar issue with GCC that was solved with the addition of a
configuration flag, but here I am at a loss.
