If existing board's .specs are used for linking of a user's application,
then instead of normally used libs like libc.a & libstdc++.a might be
requested their "nano"-suffixed siblings: libc_nano.a, libstdc++_nano etc.
That way:
----------------------------->8---------------------------
%rename link_gcc_c_sequence myboard_link_gcc_c_sequence
*myboard_libc:
%{!specs=nano.specs:-lc} %{specs=nano.specs:-lc_nano}
*link_gcc_c_sequence:
%(myboard_link_gcc_c_sequence) --start-group %G %(myboard_libc) --end-group
----------------------------->8---------------------------
Our companion newlib-nano libs are all built optimized for size, so we'd like
to use them for linking. But given linker will see "-lc_nano -lstdc++_nano"
on its command line non-suffixed libs will be ignored.
To solve it we create those "_nano"-suffixed libraries as simple symlinks to
existing libs..

As of today baremetal (AKA "Elf32") & Linux glibc toolchains are even
more important than Linux uClibc one for ARC, so adding them.
We exclude ARC Linux toolchains from Mac buils as it seem to not make
much sense and anyway glibc build for ARC700 fails,

As of today ARCompact (AKA "ARCv1 ISA") processors (mostly those are ARC770)
are not officially supported by upstream glibc as it adds quite some burden
on release ans support of yet another "architecture" port.
But given on ABI and ISA front ARCompact is very close to ARCv2 we may
easily retrofit its support off-the-tree, which we do here.
Also given amount of changes we need to apply there's a hope it will be easy
and straight-forward to apply the same to later versions of glibc.
