Yes, the most straightforward way I know of is to use crossdev to create an i[3456]86 GCC and compile it with the corresponding cross-emerge executable. It will then install to /usr/$ARCH and you should be able to copy it to your root. > Background: some time ago I converted my atom 330 system (ASUS ION) to > 64 bits.

If your determination is correct it may be best to go back to a 32bit system - unlike ARM64 processors, which seem to suffer spectacularly when operating in 32bit - early x86_64 processors may not have a penalty or be faster in the more restricted mode. When this kind of question comes up I tend to bring up the opportunity to upgrade the computer as well. This tends to have many benefits in regards to power usage and overall system responsiveness, but I understand if it's not possible. I would point out that technology is usually amortized over a 3 year period and conventional wisdom dictates if you keep a computer longer than that as a business you are losing money due to opportunity cost of using and maintaining older and slower hardware.
