FWIW, it is not enough to change the profile to activate it, you have to
also adjust your existing packages by re-emerging under the new profile.
So what you should've tried is:
emerge --update --ask --deep --newuse @world
I don't know how well switching from no-multilib to multilib is supported,
but this would've required atleast a recompilation of glibc (which
provides stub-32.h), and gcc, probably not much more than that (but I
could be wrong).
Also, a multilib profile doesn't automatically mean your system starts
building two binaries, for that you have the ABI_X86 flags which you can
control on a per-package basis.

Since rebuilding gcc and glibc takes a while, it's possible that this was
actually the best (quickest) way out.
