aarch64: Return an error on conditional branch to an undefined symbol
The fix in 7e05773767820b441b23a16628b55c98cb1aef46 introduced a PLT
for conditional jumps when the target symbol is undefined. This is
incorrect because conditional branch relocations are not allowed to
clobber IP0/IP1 and hence, should not result in a dynamic relocation.
Revert that change and in its place, issue an error when the target
symbol is undefined.
