config: introduce the KERNEL_SUPPORTS_SHARED_LIBS silent config option

The target OSes will be able to select this option if they support shared
libraries, instead of having "Build shared libaries" depend on each OS.

    10       Add support for the Signal Processing Engine.  This will set up

    11       the toolchain so that it supports the SPE ABI extensions. This

    12       mainly targets Freescale e500 processors.

    13 

    14       Setting this option will append "spe" to the end of your target

    15       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc

    16       configure/build system will know to include SPE ABI support.

    17       It will also automatically add "-mabi=spe -mspe" to your

    18       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,

    19       so you do not need to explicitly add them.
