Taking inspiration from
https://github.com/FreddieChopin/bleeding-edge-toolchain, I have a
script which runs:
../../source/${dname}/configure \
--target=${TARGET} \
--enable-languages=c \
--without-headers \
--prefix=`realpath ../../${DIR_PREFIX}` \
--libexecdir=`realpath ../../${DIR_PREFIX}/lib`
--disable-decimal-float \
--disable-libffi \
--disable-libgomp \
--disable-libmudflap \
--disable-libquadmath \
--disable-libssp \
--disable-libstdcxx-pch \
--disable-nls \
--disable-shared \
--disable-threads \
--disable-tls \
--with-newlib \
--with-gnu-as \
--with-gnu-ld \
--with-sysroot=`realpath ../../${DIR_PREFIX}/${TARGET}` \
--with-system-zlib \
--with-gmp=`realpath ../../${DIR_PREFIX}/host/${gmp_dname}` \
--with-mpfr=`realpath ../../${DIR_PREFIX}/host/${mpfr_dname}` \
--with-mpc=`realpath ../../${DIR_PREFIX}/host/${mpc_dname}` \
--with-isl=`realpath ../../${DIR_PREFIX}/host/${isl_dname}` \
--with-pkgversion=${VERSION}
(libssp is disabled as it is provided by newlib.) When compiling GCC,
an attempt to build libssp is made, and this fails with the following:

I've attempted to search for a solution, but they were all more or
less "disable libssp."
Thanks in advance,

All I've found is this has some interaction with the selection of
target (arm-none-eabi), but I don't know why or how to fix it.
