Unfortunately (last time we checked) clang didn't support enough of the
gnu99 standard to build elfutils. See the following comment for our
configure check:

# We use -std=gnu99 but have explicit checks for some language constructs
# and GNU extensions since some compilers claim GNU99 support, but don't
# really support all language extensions. In particular we need
# Mixed Declarations and Code
# https://gcc.gnu.org/onlinedocs/gcc/Mixed-Declarations.html
# Nested Functions
# https://gcc.gnu.org/onlinedocs/gcc/Nested-Functions.html
# Arrays of Variable Length
# https://gcc.gnu.org/onlinedocs/gcc/Variable-Length.html

You might want to poke the clang developers to make sure they support
those extended GNU C language features. As soon as they do, the
configure check should succeed and you should be able to use the clang
tools to build stuff.

Cheers,
