compiler: Don't support the r11 option

The r11 option was used to generate BEAM modules that could
loaded both on both R11 and R12/R13 to facilitate testing
that R11 and R13 nodes could communicate with each other.

Since R14 is only required to be compatible with R12 and
R13 nodes, the r11 option is no longer needed.
