[libdispatch-dev] Solaris portability, POSIX memalign checking in configure.ac - PATCH [1/6]

[Joakim Johansson]

Need to check whether posix_memalign exists on the target system  
(there is a patch for a future Solaris version to add it, so I'd  
rather not check for the Solaris platform, but rather for feature  
existence).

Still a lot of work remains for a working Solaris port due to the  
kqueue stuff, but here are some initial patches.
