+define Package/libatomicops/description
+ Provides implementations for atomic memory update
+ operations on a number of architectures. This allows
+ direct use of these in reasonably portable code. Unlike
+ earlier similar packages, this one explicitly considers
+ memory barrier semantics, and allows the construction of
+ code that involves minimum overhead across a variety of
+ architectures.

+Package: libatomic-ops
+Version: 1.0-3
+Tags: patch
+
+Libatomic-ops currently FTBFS on mips/mipsel because there is no
+arch-specific implementation, and the generic pthread isn't configured.
+
+The appended patch adds a basic implementation for linux.
