* builds/unix/ftconfig.in: Duplicate the cpp computation of
FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
If FT_USE_AUTOCONF_SIZEOF_TYPES is defined, the cpp computation
is disabled and the statically configured sizes are used.
This fixes Savannah bug #21250
* builds/unix/configure.raw: Add the checks to compare the
cpp computation results of the bit length of int and long
versus the sizes detected by running configure. If the results
are different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to
prioritize the results detected by running configure.
New option --{enable|disable}-biarch-config is added to
define or undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.

* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon
