Copy relocations and canonical PLT entries are for symbols defined in a
DSO. Currently we create them even for a `Defined`, possibly leading to
an output that won't work at run-time (e.g. R_X86_64_JUMP_SLOT
referencing a null symbol).
```
% cat a.s
.globl _start, main
.type main, @function
_start: main: ret
.rodata
.quad main
% clang -fuse-ld=lld -pie -nostdlib a.s
% readelf -Wr a.out
Relocation section '.rela.plt' at offset 0x290 contains 1 entry:
Offset Info Type Symbol's Value Symbol's Name + Addend
00000000000033b8 0000000000000007 R_X86_64_JUMP_SLOT 12b0
```
Report an error instead for the default `-z text` mode. GNU ld reports
an error in `-z text` mode as well.
