`R_X86_64_PLT32` is a branch relocation type which means the exact address is insignificant.

- In an executable, it can prevent the creation of a canonical PLT entry.
- In a shared object, an R_X86_64_PC32 to a preemptible symbol is not allowed.

This can be favorable since it can enable us to use `JCC_4` for tail calls.
