ELLCC updated to musl 0.9.14

[Richard Pennington <rich@pennware.com>]

Hi,

I've updated the musl version of the clang/LLVM based ELLCC compiler 
suite to use musl release 0.9.14.
As usual the musl guys have been doing a great job. The new release 
looks great!

I dis have to make a few small changes to the configure script. The main 
one was that the warning the clang gives if a warning option is not 
supported is a warning, not an error. I added -Werror to tryflag. Other 
than that I just loosened up the target names a bit.
