docs/known-issues: add the infamous "mixed implicit and normal rules"

make-3.82 now refuses to have both normal and implicit rules in the
same definition, so document the issue with a known workaround.

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

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

     9       mainly targets Freescale e500 processors.

    10       

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

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

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

    14       will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,

    15       and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you

    16       do not need to explicitly add them.
