+Add replacement for <a.out.h>
+
+Valgrind includes <a.out.h> to get the definition of 'struct
+nlist'. However, while glibc directly defines 'struct nlist' in
+<a.out.h>, uClibc relies on it being defined by kernel headers (i.e
+<a.out.h> simply includes <linux/a.out.h>). This works for most
+architectures, but not for PowerPC, on which the a.out binary format
+has never been supported, and therefore the <linux/a.out.h> kernel
+header does not exist.
+
+One solution would have been to use the <nlist.h> header, but this one
+is only available in glibc, and it also has a slightly different
+definition than the one in <a.out.h>. So, for the time being, the
+easiest solution is to just replace the #include <a.out.h> in Valgrind
+code by a copy/paste of the 'struct nlist' definition.
