        bl .LTHUNK32.lto_priv.0
        .cfi_endproc

$ cat 1.s
_ZN8CryptoPP5Weak19ARC4_Base11ProcessDataEPhPKhm:
        .globl .LTHUNK32.lto_priv.0
        .hidden .LTHUNK32.lto_priv.0
        .set   
.LTHUNK32.lto_priv.0,_ZN8CryptoPP5Weak19ARC4_Base11ProcessDataEPhPKhm
        .cfi_startproc
        .cfi_endproc

$ gcc [01].s -shared -fPIC -o libx.so -fuse-ld=bfd && nm libx.so | grep THUNK
0000000000000738 t .LTHUNK32.lto_priv.0

while ld.gold does not created the undefined symbol:

$ gcc [01].s -shared -fPIC -o libx.so -fuse-ld=gold && nm libx.so | grep THUNK
0000000000000758 t .LTHUNK32.lto_priv.0
