If media-libs/taglib-1.11 has abi_x86_32 flag, dev-libs/boost should have it as well. Otherwise there is linker error.
Boost is not a hard dependency, but when found, it will be used. I am not sure the correct way to do this; perhaps checking MULTILIB_USEDEP in pretend phase if boost is installed on the system already. There is no way to enable or disable usage of boost via their configure script.

This is already present in 1.11-r1. (In reply to A. Wilcox (awilfox) from comment #1) > Boost is not a hard dependency, but when found, it will be used.
