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.
