After rebuilding mesa with USE='-r600-llvm-compiler' 'grep libelf /var/db/pkg/media-libs/mesa-10.3.7-r1/NEEDED.ELF.2' finds nothing.

media-libs/mesa-10.3.7-r1 was built with the following:
USE="dri3 egl gallium gbm llvm nptl pax_kernel pic udev vdpau xa -bindist -classic -debug -gles1 -gles2 -opencl -openmax -openvg -osmesa -r600-llvm-compiler (-selinux) -wayland -xvmc" ABI_X86="64 -32 -x32" VIDEO_CARDS="r600 radeon -freedreno -i915 -i965 -ilo -intel -nouveau -r100 -r200 -r300 -radeonsi -vmware"

I looked into configure.ac of current git master, libelf is required only for opencl, radeonsi and r600-llvm-compiler:


if test "x$enable_opencl" = xyes; then
...
    if test "x$have_libelf" != xyes; then
       AC_MSG_ERROR([Clover requires libelf])
    fi
fi
...
radeon_llvm_check() {
...
    if test "x$have_libelf" != xyes; then
       AC_MSG_ERROR([$1 requires libelf when using llvm])
    fi
}
...
if test -n "$with_gallium_drivers"; then
    gallium_drivers=`IFS=', '; echo $with_gallium_drivers`
    for driver in $gallium_drivers; do
        case "x$driver" in
...
        xr600)
...
            if test "x$enable_r600_llvm" = xyes -o "x$enable_opencl" = xyes; then
                radeon_llvm_check "r600g"
                LLVM_COMPONENTS="${LLVM_COMPONENTS} bitreader asmparser"
            fi
...
            ;;
        xradeonsi)
..
            radeon_llvm_check "radeonsi"
..
            ;;
        esac
    done
fi
