rmodule: Add support for R_X86_64_PLT32
The recent toolchain update also updated binutils, which has a new relocation type, introduced with commit bd7ab16b (x86-64: Generate branch with PLT32 relocation). Add support for R_X86_64_PLT32, which is handled as R_X86_64_PC32. Add comment explaining the situation. Fixes build error on x86_64.
