x86: Remove linker option: -z prefix-nop
Since it is incorrect to convert
bnd call *foo@GOTPCREL(%rip)
to
bnd nop
call foo
this patch removes the "-z prefix-nop" option from x86 linker.
* emulparams/call_nop.sh: Remove -z prefix-nop.
* ld.texinfo: Likewise.
* testsuite/ld-i386/call3c.d: Check for linker error.
* testsuite/ld-x86-64/call1c.d: Likewise.
