[Bug 1707429] [NEW] Error when installing "g++-multilib libc6-dev-i386" on 64 bit machine

[bel]

Public bug reported:

I'm a software developer. I tried to build for 32 bit Linux on 64 bit Linux, to check type cast warnings occurring only for 32 bit versions. But it seems I cannot build for 32 bit on my 64 bit machine - gcc -m32 will fail with "/usr/bin/ld: cannot find -lgcc".
Googled for a solution and found https://www.cyberciti.biz/tips/compile-32bit-application-using-gcc-64-bit-linux.html
Typed "sudo apt-get install g++-multilib libc6-dev-i386".

Then an error message popped up.
