C-SKY: Use the common way to define MULTILIB_DIRNAMES.
C-SKY previously used a forked print-sysroot-suffix.sh and define
CSKY_MULTILIB_DIRNAMES to specify OS multilib directories. This
patch delete the forked print-sysroot-suffix.sh and define
MULTILIB_DIRNAMES to generate same directories.
gcc/
* config.gcc: Don't use forked print-sysroot-suffix.sh and
t-sysroot-suffix for C-SKY.
* config/csky/print-sysroot-suffix.sh: Delete.
* config/csky/t-csky-linux: Delete.
* config/csky/t-sysroot-suffix: Define MULTILIB_DIRNAMES
instead of CSKY_MULTILIB_DIRNAMES.

-# This shell script produces a header file fragment that defines
-# SYSROOT_SUFFIX_SPEC. It assumes that the sysroots will have the same
-# structure and names used by the multilibs.
-
-# Invocation:
-# print-sysroot-suffix.sh \
-# MULTILIB_OSDIRNAMES \
-# MULTILIB_OPTIONS \
-# MULTILIB_MATCHES \
-# > t-sysroot-suffix.h
-
-# The three options exactly correspond to the variables of the same
-# names defined in the tmake_file fragments.
-
-# Example:
-# sh ./gcc/config/print-sysroot-suffix.sh "a=A" "a b/c/d" ""
-# =>
-# #undef SYSROOT_SUFFIX_SPEC
-# #define SYSROOT_SUFFIX_SPEC "" \
-# "%{a:" \
-# "%{b:A/b/;" \
-# "c:A/c/;" \
-# "d:A/d/;" \
-# ":A/};" \
-# ":}"

-# The script uses temporary subscripts in order to permit a recursive
-# algorithm without the use of functions.
