[OE-core] [PATCH 1/1] tune-ppce500v2.inc: explicitly set gcc float

[Hongxu Jia]

For powerpc*-*-*spe*, default to with_cpu=8548 if --enable-e500-double,
and to 8540 otherwise.
vim gcc/config.gcc
...
    powerpc*-*-*spe*)
      if test x$enable_e500_double = xyes; then
         with_cpu=8548
      else
         with_cpu=8540
      fi
      ;;
...

The with_cpu is used for SPE version detection
vim ./gcc/config/rs6000/t-linux
...
  7 ifneq (,$(findstring spe,$(target)))
  8 MULTIARCH_DIRNAME := powerpc-linux-gnuspe$(if $(findstring 8548,$(with_cpu)),,v1)
  9 else
 10 MULTIARCH_DIRNAME := powerpc-linux-gnu
...

The variable MULTIARCH_DIRNAME is the output of '$CC --print-multiarch'.
Without this patch, the output is 'powerpc-linux-gnuspev1' which caused
python3 do_configure failed.

Since ppce500v2 -mcpu is 8548, explicitly add --enable-e500-double could fix
the issue.
