It looks like the program called 'c++' (is it GCC? clang?) is either 
not passing the -arch option down to 'ld' or 'ld' does not respond to 
it.

You might try adding

  LDFLAGS=-Wl,-arch,x86_64

and/or add '-v' to CXXFLAGS to cause the compiler to dump the details 
of what it is doing so you can see the arguments it is passing to the 
linker.

Also please check that ./.libs/libxqilla.a really does contain 64-bit 
objects.  Some linkers use the mode from the first object file they 
encounter.
