Extended Description

OpenSSL's aes-x86_64.s does something like

    movq T-S, %rax

    .globl T

T:

    .globl S

S:

This results in a R_X86_64_PC32 text relocation, which GNU ld doesn't like. Runnning the same code through GNU as doesn't result in a relocation, e.g. the difference is handled internally. Same for using . in place of S.
