Fail at pkg_pretend() for now.

It may be true that Clang does not support 16-bit assembly, but `as` is still called: configure.ac: if ! echo '.code16;.text;addr32 pushw 4(%esp)' | as -o dummy.o >/dev/null 2>&1; then echo '' echo '*** error:' echo '*** Your system has no complete code16 functional gas,' echo '*** you must upgrade to at least binutils-2.9.5' echo '*** in order to compile DOSEMU ... giving up' echo '' exit 1 fi
Actually I found that there is a patch (dosemu-1.4.1_pre20130107-as.patch) which fixes this.

It's not clear if the patch does not apply to you or you have a stale ::gentoo tree locally.
Let's close it as pkg_pretend() now clearly states the prerequisite $CC.
