Ezequiel Garcia bd8dd776db Add support for Altera's Nios-II softcore architecture
This commit adds strace support for Altera's Nios-II.  The architecture
is supported by Linux since v3.19, and it implements the generic syscall
ABI.

* configure.ac: Add nios2 support.
* cacheflush.c [NIOS2] (sys_cacheflush): New function.
* linux/nios2/*: New Nios-II specific files.
* Makefile.am (EXTRA_DIST): Add them.
