sys-devel/llvm-3.7.1-r3::gentoo was built with the following:
USE="libffi ncurses static-analyzer -clang -debug -doc -gold -libedit -lldb -multitarget -ocaml -python -test -xml" ABI_X86="64 -32 -x32" PYTHON_TARGETS="python2_7" VIDEO_CARDS="radeon"
Comment 3 Camusensei 2016-09-18 18:51:08 UTC 
For some reason, emerge --info does not reflect me trying to build it into the 32 ABI. So I'm telling this here.
Comment 4 Christophe PEREZ 2017-05-25 05:09:43 UTC 
exactly same error with sys-devel/llvm-3.9.1-r1 and sys-devel/gcc-5.4.0-r3 on a fresh install.
Comment 5 RJ 2017-10-05 07:56:44 UTC 
I can also confirm.

The problem is that cmake is detecting headers (not just malloc_np.h) that aren't really there.  I wasn't able to figure out why this was the case.  It doesn't appear to be an incorrect environment variable or permissions problem....

Here is a workaround:

cd /usr/portage/sys-devel/llvm

ebuild llvm-3.7.1-r3.ebuild clean configure

cd /var/tmp/portage/sys-devel/llvm-3.7.1-r3/work/llvm-3.7.1.src-.arm

sandbox # enter sandbox

source ../../temp/environment # get build environment variables

rm CMakeCache.txt # remove cached cmake that found non-existent headers

# reconfigure
