First you have to check whether the script itself uses relative or
absolute paths, otherwise you will actually need a whole new script.
Scripts in /usr/share/ are usually not aware of the changes needed to
allow for cross-configuration.

No. /usr/lib/ and /usr/include only. /usr/share/ is *meant* to be
architecture-independent.

dpkg-cross is not a one-stop solution for the support of cross-building
for all packages in Debian. Some packages simply need specialised
wrappers and/or upstream changes/patches. dpkg-cross exists for
common-case solutions based around cross-compilation, not every single
broken package.
