Cannot build first stage gcc for a configured cross-compiler

I'm trying to build a gcc cross-compiler from source, and whenever I try to build the first stage gcc it results in multiple errors. I'd appreciate any help!

Ubuntu 18.04.3 LTS
gcc-7.5.0
autoconf-2.69

./configure options
--target=arm-none-eabi
--prefix=/usr/bin/crossbuild
--without-headers
--enable-multilib
--with-multilib=armv7e-m
--with-gnu-as
--with-gnu-ld
--with-dwarf2
--with-newlib
--with-system-zlib
--without-libffi
--disable-decimal-float
--disable-nls
--enable-languages="c,c++"
--enable-interwork
--disable-libstdcxx-pch 
--with-newlib
