That is something you will need to be sure of if you are unable to build 
Squid natively on the device. Squid can be cross-built from another 
machine, but you need to have used the right CPU-arch tuplets in the 
--host and --build cross-build options to run the resulting binaries.

If you don't already know what I mean by cross-build and tuplets you 
have some research to do before starting. :-)
OpenWRT has some fairly up to date info 
<https://forum.openwrt.org/viewtopic.php?id=52968>, not sure about Entware.

CPU arch should only matter to your build tools so they can produce 
binaries that run on the device. That is a general code building thing.

The issues specifically with building Squid will be whether you have 
support in that devices OS for the Squid features you want to use.

Run 'squid -v' to retrieve the build options from an existing Squid if 
you have or can find one for the device. Then figure out which ones you 
want in your build.

Just the OS NAT interface. Sometimes that is a library (eg Linux 
netfilter), sometimes just the getsockopt() kernel API (eg OpenBSD).
