x86; Allow IFUNC pointer defined in PDE
If IFUNC symbol is defined in position-dependent executable, we should
change it to the normal function and set its address to its PLT entry
which should be resolved by R_*_IRELATIVE at run-time. All external
references should be resolved to its PLT in executable.

I have observed the following failure on aarch64-none-linux-gnu
succeeded with: <>, expected: <.*dynamic STT_GNU_IFUNC symbol `foo' with
pointer equality in `.*.o' can not be used when making an executable; recompile
with -fPIE and relink with -pie>
FAIL: ld-aarch64/ifunc-9
I have also observed some of the new tests failing:
FAIL: Build pr23169a
FAIL: Build pr23169d
FAIL: Run pr23169a
FAIL: Run pr23169d
