+Patch borrowed from OpenEmbedded, available at
+recipes/libaio/libaio-0.3.106/00_arches.patch in their source
+tree. The patch has been adapted to remove the ARM-related
+definitions, since they have been merged in later versions of libaio.
+
+The patch adds various architecture specific definitions (syscall
+number and macros) for m68k, MIPS, PA/RISC and Sparc. Amongst these,
+Buildroot mostly only cares about MIPS, but it was just easier to take
+the whole OpenEmbedded patch.
