strace: fix building for arc, metag, nios2, or1k and tile

Following commit broke building for arc, metag, nios2, or1k and tile:
http://sourceforge.net/p/strace/code/ci/34683e3926d8c2daa368afb805da422ee7043396/

Now we're fixing that breakage with a back-port of upstream fix:
http://sourceforge.net/p/strace/code/ci/dd1a80c8d213eed95fe55b7ebcb07ee165dd8e4b/

Mentioned fix will be a part of the next strace release,
i.e. this patch must be removed on strace version bump.

+Subject: [PATCH] arc, metag, nios2, or1k, tile: fix build
+
+Fix build regression introduced by commit
+34683e3926d8c2daa368afb805da422ee7043396.
+
+* linux/32/syscallent.h: Add sys_ prefix to ARCH_mmap and mmap.
+* linux/arc/syscallent.h: Add sys_ prefix to ARCH_mmap and mmap_pgoff.
+* linux/nios2/syscallent.h: Likewise.
+* linux/or1k/syscallent.h: Likewise.
+* linux/tile/syscallent1.h: Add sys_ prefix to ARCH_mmap and sys_mmap_4koff.
+* pathtrace.c (pathtrace_match): Handle SEN_ARCH_mmap.
+
+This is a back-port of upstream commit
+http://sourceforge.net/p/strace/code/ci/dd1a80c8d213eed95fe55b7ebcb07ee165dd8e4b/
+
+It should be removed upon the next bump of strace version.
