It is advantageous for ff_crop_tab, as the base pointer used to
access this table is not the first element of it. But the real
base pointer is still at a constant offset from the code/the GOT
and can therefore be accessed relative to the instruction pointer
(if supported by the arch) or relative to the GOT; without this,
one has to first load address of ff_crop_tab (potentially via
the GOT) and then offset manually (which is what the earlier code
did).
