--- Comment #3 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Gah, I ran into the same issue on gcc92.
I 'configure'd '--with-arch=rv64imafdc --with-abi=lp64d --enable-multilib'.

That seems to be the case indeed; at least I'm not seeing any 'if_multiarch'
etc. in 'gcc/config/riscv/'.
$ find /usr/include/ -name libc-header-start.h
/usr/include/riscv64-linux-gnu/bits/libc-header-start.h
Also, do potentially further distribution packages have to be installed, for
additional multilibs? Like I have on an Ubuntu x86_64 GN/Linux system:
$ find /usr/include/ -name libc-header-start.h
/usr/include/i386-linux-gnu/bits/libc-header-start.h
/usr/include/x86_64-linux-gnu/bits/libc-header-start.h
$ dpkg -S /usr/include/i386-linux-gnu/bits/libc-header-start.h
/usr/include/x86_64-linux-gnu/bits/libc-header-start.h
libc6-dev:i386: /usr/include/i386-linux-gnu/bits/libc-header-start.h
libc6-dev:amd64: /usr/include/x86_64-linux-gnu/bits/libc-header-start.h
