Vassil Vassilev 4fa39ba82f Do not resolve symbols from executables compiled with -fPIE. 
Executables that are compiled with fPIE means they are compiled in a position
independent manner and are almost indistinguishable from the shared objects. A
reasonably reliable way to find if this was a `pie executable` is to check the
`DF_1_PIE` in the dynamic section of ELF.

The pseudo-code is:
```
if DT_FLAGS_1 dynamic section entry is present
  if DF_1_PIE is set in DT_FLAGS_1:
    print pie executable
  else
    print shared object
```

See https://stackoverflow.com/questions/34519521/why-does-gcc-create-a-shared-object-instead-of-an-executable-binary-according-to/34522357#34522357

Fixes root-project/root#7366
