I didn't explicitly enable checking. The full configure command I ran with
(from -freport-bug output) is:
/scratch/tc-testing/tc-nov-30-trunk/build-rv64gcv/../gcc/configure
--target=3Driscv64-unknown-linux-gnu
--prefix=3D/scratch/tc-testing/tc-nov-30-trunk/build-rv64gcv
--with-sysroot=3D/scratch/tc-testing/tc-nov-30-trunk/build-rv64gcv/sysroot
--with-pkgversion=3Dg18d8a50a042 --with-system-zlib --enable-shared --enabl=
e-tls
--enable-languages=3Dc,c++,fortran --disable-libmudflap --disable-libssp
--disable-libquadmath --disable-libsanitizer --disable-nls --disable-bootst=
rap
--src=3D../../gcc --enable-multilib --with-abi=3Dlp64d --with-arch=3Drv64im=
afdc
--with-tune=3Drocket --with-isa-spec=3D20191213 'CFLAGS_FOR_TARGET=3D-O2=20=
=20=20
-mcmodel=3Dmedlow' 'CXXFLAGS_FOR_TARGET=3D-O2    -mcmodel=3Dmedlow'

I built the toolchain using riscv-gnu-toolchain `make linux`.=
