This is part of an attempt to generate an arm-none-eabi toolchain, and then integrate those changes back into crossdev (TARGET=arm-none-eabi):
| Code: | ../../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=${VERSION}
make -j${NCPU} -l${NCPU}
make install |
This occurs, also for 7.2.0, with or without the Gentoo-provided patches applied:

Notably libssp is disabled. Searching for this issue that seems to be the proposed solution (GCC 6.x era). Changing the configure script calls to avoid a custom directory should work, the only thing generated before this that had the TARGET set was binutils:
| Code: | ../../source/${dname}/configure \
--target=${TARGET} \
--prefix=`realpath ../../${DIR_PREFIX}` \
--docdir=`realpath ../../${DIR_PREFIX}/share/doc` \
--disable-nls \
--enable-interwork \
--enable-multilib \
--enable-plugins \
--with-system-zlib \
--with-pkgversion=${VERSION}
make -j${NCPU} -l${NCPU}
make install
