[PATCH] Don't print (PLT) on ARM

[Peter Smith via llvm-commits]

Hello Renato, Rafael,

If it is any help, I think the only way you can generate R_ARM_PLT32
is with an old GNU assembler targeting a pre-ABI target. I'd be
surprised if llvm claimed any support for pre-ABI targets.

>From https://sourceware.org/binutils/docs/as/ARM_002dRelocations.html
"For compatibility with older toolchains the assembler also accepts
(PLT) after branch targets. On legacy targets this will generate the
deprecated `R_ARM_PLT32' relocation. On EABI targets it will encode
either the `R_ARM_CALL' or `R_ARM_JUMP24' relocation, as appropriate."
