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..
