With '-m32' the 32-bit libraries in '/usr/lib' will be used ! The
'/usr/lib64' has
the 64-bit x86_64 libraries!
Maybe your Gentoo is a "custom" Linux with unstandard conventions?
The Ubuntu Linux/x86_64 is this kind of "custom" Linux where the 64-bit
libs are in '*lib' and the 32-bit libs in '*lib32'. The Fedora, SuSE
etc. then
use the convention which the GCC sources assume a Linux/x86_64, or any
other 64-bit Linux using ('mips64-linux-gnu', 'ppc64-linux-gnu',
'sparc64-linux-gnu',.....)
