Feature #17647: Print register `r11` on 32-bit ARM Linux

In (32-bit) ARM, register r11 is a general purpose register which is often used as the frame pointer (fp), and there seems no reason not to print the value of it. In fact, the value of the (potential) frame pointer is printed for every other architecture; x29 (or fp in Apple) in Aarch64, EBP in i386, RBP in x86_64, and s0 in RISC-V.
