In case we build for ARC core which has no support of atomic ops among
other things we need to configure libc to use Linux kernel helper to emulate
HS atomic ops. This is done with disabling of CONFIG_ARC_HAS_ATOMICS in uClibc.
Currently we __remove__ this option from .config but this makes no sense as
its default state is "y" so we need to explicitly disable it instead.

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

On cygwin, creating both "foo.exe" and "foo" results in 'ln -sf'

After the release, xldd will be modified to query the compiler for

It turns out buildroot does not currently accept a toolchain where a dynamic

make's configure uses pkg-config to detect if Guile should be enabled;
on ArchLinux, this picks up Guile from build machine's pkgconfig and then
it fails to compile.
A better solution might be to create a ${CT_HOST}-pkg-config in
buildtools/bin that would report "unsupported" for all packages.
However a quick grep only showed pkg-config being used by GCJ
(not sure if it will build in canadian cross - we don't have any
samples with GCJ) and Blackfin simulator in GDB (Blackfin is not
currently supported by crosstool-ng). Hence, leave such pkg-config
