Ooookay, where to start.

One, if you start with TERM=linux that means you are on a Linux text console - which quite definitely is NOT an X terminal of any sort.

Two, having just reproduced the "problem" by logging in on tty2, seting TERM=xterm and running Midnight Commander, I could also see that "Esc 2", "Esc 3" and so on continued to work fine in spite of corresponding Function keys not being recognised - meaning that the problem clearly lies not with mc itself but with the terminal's inability to generate appropriate codes.

Three, terminals are in general supposed to set TERM to a correct value by themselves and changing this by hand is something one does at one's own risk.
