PR22374 testcase, function pointer references in .data
Function pointer references in .data ought to use a dynamic reloc.
There shouldn't be any need for a PLT entry and definitely no copy
reloc.
This test fails on quite a few targets, but isn't something that
anyone should worry about too much. It's really just a missed
optimization.
