* Add support for the C-SKY processor series.
+* -t now doesn't report members within archives, unless -t is given twice.
+ A single -t is now more useful when generating a list of files that should be
+ packaged for a linker bug report. For example:
+ gcc hello.c -save-temps -Wl,-t | xargs realpath | sort | uniq > files
+ tar cJf test.tar.xz `cat files`

Changes in 2.31:
* Speed up direct linking with DLLs for Cygwin and Mingw targets.
