[uClibc]memalign &c

[Miles Bader]

I've added a `memalign' function to my malloc implementation.

The standard functions `valloc' and `posix_memalign' should probably be
implementation-independent wrappers around memalign in libc/stdlib
(malloc-930716 doesn't currently implement `memalign', but I guess maybe
one can be stolen from glibc's malloc or something... I don't know).
