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.
