ELF64: PLT32, GOTPCREL, and GOTPCREL64 really need exactitude

Browse Source 
Now when the assembler is properly generating the address that we push
down to the backend, enable requesting an exact value for these
relocations (these are pointing to a specific GOT or PLT slot; the
addend is used to adjust the computed value in the instruction, not
for offset for the symbol.)
