Alexey Neyman 413f5f6100 Super-H multilib toolchain fixes
1. On SuperH, configuring GCC with explicit variant of the CPU
(like "sh4") limits the default set of multilibs to just that CPU
and requires --with-multilib-list to change. Allow for "unspecified"
variant, so that we can defer to GCC to determine the list.

2. Support toolchains with both endiannesses at the same time.

3. Add a SuperH/newlib sample

4. Add more flags processing for uClibc

Add support for the Signal Processing Engine. This will set up
the toolchain so that it supports the SPE ABI extensions. This
mainly targets Freescale e500 processors.
Setting this option will append "spe" to the end of your target
tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
configure/build system will know to include SPE ABI support. It
will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
do not need to explicitly add them.
