[Bug-gsl] Compiling 1.9 for different Endian target

[Scott Buchanan]

Was compiling 1.9 for universal binary on OS X and ran into a compile  
problem with ieee-utils/fp.c.  I was compiling on an intel Mac so the  
configure had defined HAVE_DARWIN86_IEEE_INTERFACE  This is fine for  
the i386 target but not for the ppc target.

My workaround was to hand edit the config.h file and add the  
following (the first line was put there by .configure.

#define HAVE_DARWIN86_IEEE_INTERFACE 1
#ifdef __BIG_ENDIAN__
#undef HAVE_DARWIN86_IEEE_INTERFACE
#define HAVE_DARWIN_IEEE_INTERFACE 1
#endif

This takes advantage of the gcc preprocessor __BIG_ENDIAN__ that's  
available.

Thanks.
