Thanks for the report. It compiles if I unset AS and ASPP in src_configure:

	unset AS
	unset ASPP
	econf "${opt[@]}"

Or the user could unset these by say creating a file:

/etc/portage/env/unset-AS-unset-ASPP

containing:

unset AS
unset ASPP

and in /etc/portage/package.env:

dev-lang/ocaml unset-AS-unset-ASPP

Have you tried this?

As I have said in other bugs, you can't unset variables in /etc/portage/package.env

AS="llvm-as" is wrong. llvm-as can only process LLVM IR as the help say:

llvm-as --help
OVERVIEW: llvm .ll -> .bc assembler

You can try AS="clang" instead.
