Me never having used clang and you not providing sufficient informations 
to be able to help, only 2 general remarks:

* General answer from the "top autoconf newbie answering templates' drawer":

Do as autoconf tells you - "See 'config.log' for details"


* Knowing you are building on x86_64, your log message referring to 
/usr/lib/clang-ananlyser indicates your "clang"-package is likely 
misconfigured/incorrectly installed.
