How so? a) it's not -rpath, and doesn't do something very relevant to
the produced binary except add a search path for dependencies of
dependencies b) LD happily ignores libraries it finds in the various
search paths when they are not for the right architecture.

The worst that happens is that you get warnings like:
/usr/bin/ld: skipping incompatible /usr/lib/i386-linux-gnu/libnss3.so when searching for -lnss3
