Yes, but Björn reports that -largs doesn't work if you're building a
dynamic library!

   $ gprbuild -Pbc -largs -Wl,-foo
   gprlib bc.lexch
   /opt/gnat-gpl-2011/bin/gcc \
   -dynamiclib -Wl,-flat_namespace -shared-libgcc \
   -o /Users/simon/sf/booch95/lib-release//libbc.dylib \
   -L/opt/gnat-gpl-2011/lib/gcc/x86_64-apple-darwin10.2.0/4.5.3/adalib/ \
   -lgnarl-2011 -lgnat-2011 [...]

vs

   $ gprbuild -Pbc --config=botched.cgpr
   gprlib bc.lexch
   /opt/gnat-gpl-2011/bin/g++ \
