H.J. Lu 74437ea28f i386: Issue an error on non-PIC call to IFUNC in PIC object
On i386, IFUNC function must be called via PLT.  Since PLT in PIC
object uses EBX register, R_386_PLT32 relocation must be used to
call IFUNC function even when IFUNC function is defined locally.
Linker should issue an error when R_386_PC32 relocation is used
to call IFUNC function.

Since PR ld/19784 tests doesn't use PLT relocation to local IFUNC
function, they are moved to the x86-64 test directory.
