Don't do that, since binutils-2.9.1.0.x doesn't support such syntax
as "lcall *(%edi)". I don't know why binutils-2.9.5.0.x does want to
give you so unnecessary warnings, though.
For binutils developers: Why does newer GAS warn formats like "lcall
(%edi)"? AFAIK, binutils-2.9.1 only supports such formats and it fails
when it encounters "lcall *(%edi)" or similar. I think it is
consistent with the other formats to prepend an asterisk to an absolute
call or jump operand which uses a register as well, but even GCC
generates absolute call/jump operands without `*', so isn't it too
strict to raise warnings?
