On my Blackberry browser, at the bottom of every mobile page is a link to the full version.
It looks like it just appends &force-full-site=1 to the end of the URL.
ex. http://www.amazon.com/?ie=UTF8&force-full-site=1
If you're looking for a way to completely disable the mobile version you would have to set your mobile browser to identify itself as a desktop browser. That is, spoof the user-agent in Opera Mini (no idea if that's possible, it is on my BB).
The Amazon website appears to redirect based on the user-agent of the browser, and can be overridden by the url option.
You could choose to order locally and deliver internationally. Generally, you can just change the web site from their country to yours.
For example, if you wanted to buy this book set. Click on the item, you will have the following URL with loads of rubbish after it:
http://www.amazon.com/Song-Ice-Fire-4v-Thrones/dp/034552905
Change the web site like so:
http://www.amazon.com/Song-Ice-Fire-4v-Thrones/dp/034552905
And it will come up on the US site where you can order as normal.
Note that sometimes, the URL looks like this instead:
http://www.amazon.co.uk/gp/product/0345529057/
This doesn't always work, if it fails, take that number at the end (sometimes a combination of numbers and letters), that is the Amazon product id, you can search for it directly. It is normally consistent across countries. Not everything is available in every region of course.
If, however, you are doing a lot of giving, you may find it easier to register for an Amazon account in that country. That way you can order local to the recipient and save loads on shipping.
You may find though that having a US-based account is useful anyway and shipping rates from there may sometimes be less anyway. You can be a non-US citizen and still have an account with Amazon US - at least you could when I signed up a few years ago.
Other than that, I'm not aware of another tool that lets you do what you want.

Whenever you search for a product you'd find a unique ASIN number for every product at the bottom of the product page(ASIN is same for any domain), just use that ASIN number in search box in the domain you prefer, you'll find the product if it is available.
