Not suiteable for upstream, but get's rid of the
nasty redefines for:
                 from ./tif_config.h:10:
/usr/include/sys/feature_tests.h:250: note: this is the location of the previous definition
  250 | #define _FILE_OFFSET_BITS       32

If compiled for 32 bits.
Trick is, not do it where it's wrong defined, because later on
the configure script will bail out at some cpp test.
So we do the sed right before all config files are processed.
