gdk-pixbuf: add an option so that loader errors are fatal

So that gdk-pixbuf-query-loader failures can be identified as such (and executed
later, or run on the target) add a magic environment variable return loader
failures from main().

gdk-pixbuf: pass GDK_PIXBUF_FATAL_LOADER where relevant

Pass GDK_PIXBUF_FATAL_LOADER to the sstate postinst and intercept so that any
problems are flagged as errors instead of being silently ignored.

Make ppce300c3 tune hard-float by default

The tuning file for PowerPC e300c3 is soft-float. In OE-classic it was hard-
float and it should be as the c3 has an fpu. I have modified the tuning file
to include both a hard-float version (using the existing ppce300c3 name) and
an optional soft-float version (called ppce300c3-nf).

The following patch also passes a "--with-cpu=e300c3" argument to GLIBC.
For this to have any effect the sqrt/sqrtf implementations added by the
"glibc.fix_sqrt2.patch" are required and also an additional "Implies" file
(added to the mentioned patch as a separate patch for eglibc_2.19).

Tested with eglibc 2.19 on PowerPC MPC5125.
