[libprefix] Add addr32 prefix required by older assemblers
Explicitly state that we are using 32-bit addressing in 16-bit code.
GNU as 2.15 (FreeBSD/amd64 7-STABLE) got confused that 32-bit registers
are used in the code that was declared as 16-bit. Add explicit modifier
'addr32' to make assembler happy.
