newlib-nano: Add option to copy libs into target

Add an option that will install a copy of newlib-nano lib*.a file in
the target dir but renamed with a nano.a suffix (eg: libc_nano.a) as
some default nano.spec files from newlib expect this setup.

Additionally the newlib-nano version of newlib.h will get copied to
include/newlib-nano/newlib.h.
