[lld] relocation R_AARCH64_ABS64 cannot be used against local symbol

[eastB233]

My test case is

.text

.global gf_vect_mad_neon
.type gf_vect_mad_neon, %function

x_const         .req    x0
q_tmp           .req    q1

gf_vect_mad_neon:
        ldr     x_const, =const_tbl
        ldr     q_tmp, [x_const]
        ret

.section .data
.balign 8
const_tbl:
        .dword 0x0000000000000000, 0x0000000000000000
        .dword 0xffffffffffffffff, 0xffffffffffffffff

It is okay when I use ld but fails with lld (I use LLVM 17)

$ clang test.S -c
$ clang test.o -fPIC -shared -o libtest.so
# It is okay

$ clang test.o -fPIC -shared -o libtest.so -fuse-ld=lld
ld.lld: error: relocation R_AARCH64_ABS64 cannot be used against local symbol; recompile with -fPIC
>>> defined in test.o
>>> referenced by test.o:(.text+0x10)
clang: error: linker command failed with exit code 1 (use -v to see invocation)

$ clang test.o -fPIC -shared -o libtest.so
$ objdump -DR libtest.so

It seems ld will transform R_AARCH64_ABS64 to R_AARCH64_RELATIVE in some way.

And I find https://reviews.llvm.org/D17265 may do the same thing.
