libc/newlib: fix host/target confusion

newlib handles the build/host/target a bit differently as one would expect:
build : not used
host : the nachine that builds newlib
target : the machine on which newlib will run

    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.
