/usr/lib/gcc/i486-linux-gnu/4.6/rts-native/adalib contains *.ali, *.a,
and a link to *.so, so it has everything gprbuild needs.
However, that *.so is for a particular target (the same as the host). I
guess that makes sense; anything else would be a cross compiler.
So the compilers.xml patch doesn't depend on the multiarch target, which
simplifies things.
