Cheesy kconfig stuff:
- silent/quiet/verbose build:
- ct-ng by default only prints quit messages, such as "CC xxx",
- if using V=0, nothing is printed,
- if using V=1, the full command lines are printed,
- other values are indeterminate,
- should help in debugging the kconfig stuff;
- complete kconfig/{,m}conf generation:
- fully dynamic dependencies on source files,
- compilation of .c into .o, then linking (instead of direct linking),
- VPATH usage when not --local;
Typo + a coment moved.

      Add support for the Signal Processing Engine.  This will set up
yann@815
    17
      the toolchain so that it supports the SPE ABI extensions. This
yann@815
    18
      mainly targets Freescale e500 processors.

      Setting this option will append "spe" to the end of your target
yann@815
    21
      tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
yann@815
    22
      configure/build system will know to include SPE ABI support.
yann@815
    23
      It will also automatically add "-mabi=spe -mspe" to your
yann@815
    24
      TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
yann@815
    25
      so you do not need to explicitly add them.
