This sounds like a typical problem you will run into when cross
compiling your stack, pkg-config is another example.
There are probably a number of techniques you can use, and one
option to consider is to just actually build on the target
arch. If you must cross-compile, one project which I've
used with success is buildroot[0], this solves the said problem
by building two stacks, one 'staging' stack which contains
tools compiled for the build host arch, and then the target
stack which is cross compiled, executing binaries from the
'staging' build directory.
