We should document this limitation and update -fno-jump-tables documentation:
'-fno-jump-tables'
Do not use jump tables for switch statements even where it would be
more efficient than other code generation strategies. This option
is of use in conjunction with '-fpic' or '-fPIC' for building code
that forms part of a dynamic linker and cannot reference the
address of a jump table. On some targets, jump tables do not
require a GOT and this option is not needed.
