There are 3 families of Synopsys DeisgnWare ARC processors:
ARCompact/ARCv1 (32-bit), ARCv2 (32-bit) and ARCv3 (32-bit
and 64-bit targets). Upstream Newlib supports only ARCv1/2.
This commit prepares ARCv1/2 libgloss port to be reused by
ARCv3 port (except crt* files). Note that __ARC64__ macro
stands for all ARCv3 targets.

According to GCC documentation for ARC, a function marked with
the long_call attribute is always called using register-indirect
jump-and-link instructions, thereby enabling the called function
to be placed anywhere within the 32-bit address space.
exit_halt function is provided by crt0.S and it's used
in nsim-syscalls.c. Thus, we want to ensure that a linkage
issue will not arise.
