Is this an expected behavior now?

```
module test
  integer, allocatable :: glob(:)
contains
  subroutine proc()
    if (allocated(glob)) print *, 'allocated'
  end subroutine proc
end module test
```

```
$ flang -c -fPIC -fPIE pic.f90
$ flang -shared pic.o -o lib.so
.../../../../../bin/ld: pic.o: warning: relocation against `_QMtestEglob' in read-only section `.text'
.../../../../../bin/ld: pic.o: relocation R_X86_64_PC32 against symbol `_QMtestEglob' can not be used when making a shared object; recompile with -fPIC
