There is a special interface built in ARC simulators (such as
nSIM) called MetaWare hostlink IO which can be used to implement
system calls. This commit adds support for this interface to the
ARC port of libgloss.
Here is an example of using this interface:
$ arc-elf32-gcc -mcpu=hs -specs=hl.specs main.c -o main
$ nsimdrv -tcf $NSIM_HOME/etc/tcf/templates/hs48_full.tcf main
Hello, World!
