I'm assuming that host and target are x86_64-unknown-linux-gnu (those
are good to specify in a report.)

Note -m32 in this command.

It's trying to link a 32 bit libgcc, but you don't have the libc items
required to be able to link 32 bit code.  By default gcc on x86_64-linux
is biarch and multilibbed, which means respectively that it accepts the
-m32/-m64 switches to select the mode and that it builds both 32 and 64
bit versions of all the support libraries.

You need to install your distro's 32 bit libc-dev package, or you need
to --disable-multilib which will result in a compiler that doesn't
support 32 bit mode.
