gem5/ext/softfloat/SConscript
Xuan Hu 461520d0ab ext: Update softfloat to 3d full version 
* Add all softfloat source files without any change.
* Remove useless file softfloat.mk.in, since gem5 use Scons.
* Add `use_fast_int64` in SConscript to distinguish src of two strategies for data
  larger than 64 bits.
  * The SoftFloat library uses two strategies to handle data larger than 64bit. One is
    spliting data into `fast_int64`, and the other is using pointer. Two strategies
    are distinguished by macro `SOFTFLOAT_FAST_INT64`. But not all "*.c" files are
    guarded by this macro, which leads to including useless files in compiling progress
    and compiling error. `use_fast_int64` used in SConscript can exclude unnecessary
    files.
