The ifunc supports are not available on binutils 2.39, so the ifunc tests

are failed. The " LoongArch: Add pointer mangling support" patch was tested

with ifunc disabled.

The full tests were all passed by using binutils master branch. If there

are no any other comments, I will include this patch.
