scripts: use the hardfloat option to set configure and CFLAGS

When hardfloat is selected, we need to pass that selection down to
./configure and in the CFLAGS.

     4 ARMV5 can use STRD and LDRD access instructions but these accesses need to be 
     5 8 byte aligned. The dynamic linker's malloc needs to match this so structures
     6 become 8 byte aligned to void unaligned accesses.
