This approach seems odd to me. I have been doing cross-compiling for
a long time. I have found Ian's approach works much better. When I
install for cross-compiling, I do

# make install DESTDIR=/var/tmp/foo

Then I copy things from /var/tmp/foo to the right places for cross
compiling. In many cases, you really don't want to mimic the native
directory structure for cross compiling.
