It worked for me. I have RISC-V Fedora Linux Ada compiler binaries
that I built cross from an x86_64 Ubuntu 18.04 system.
You should only see the gas error if your gas sources are in the same
source tree as your gcc sources. if you have separate binutils and
gcc source trees, the build should work. In the gcc/configure.ac
file, see the in_tree_gas and in_tree_gas_elf variables, which are set
if gas/ELF gas are in the same source tree. And then look at
configure, and note that configure makes assumptions about gas
features when these variables are set, instead of doing run-time
I've done number of canadian cross compiler builds, and I've never run
into this gas problem in any of them, but I always use separate
binutils and gcc source trees for my builds.
