[LLVMdev] configure with clang vs gcc

[reed kotler]

I need to leave soon and will take a look in the morning.

I did look at the autoconf input files configure.ac

There is a disable-zlib but not a disable-valgrind, even though it seems 
like there used to be.
You can find scripts on the internet when you google of people adding 
disable-valgrind to configure.

I can probably implement disable-valgrind in configure.ac.
