The problem is this test, it doesn't return true when you are exactly in
/usr/src. The result is that clang doesn't get built in the cross-tools
stage, and /usr/bin/clang is used instead for the rest of the world.
This clang will include files from /usr/include, and link with libs from
/usr/lib, causing the problem you are seeing.
You could write the test as follows instead:
.if ${.CURDIR:M/usr/src} || ${.CURDIR:M/usr/src/*} || ${.CURDIR:M/usr/obj} ||
${.CURDIR:M/usr/obj/*}
or if you insist on using empty():
.if !empty(.CURDIR:M/usr/src) || !empty(.CURDIR:M/usr/src/*) ||
!empty(.CURDIR:M/usr/obj) || !empty(.CURDIR:M/usr/obj/*)
or any other form which includes /usr/src and /usr/obj 'top level' in
addition to /usr/src/* and /usr/obj/*. If you don't care about
strictness, you could just use:
.if ${.CURDIR:M/usr/src*} || ${.CURDIR:M/usr/obj*}

Here, it is better to use the idiom mentioned on:
http://wiki.freebsd.org/BuildingFreeBSDWithClang
e.g.:
.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
.if !defined(CPP) || ${CPP} == "cpp"
CPP=clang-cpp
.endif
I know it looks ugly, but it is required for stable/9, because I was not
given permission to MFC r227120 yet, which fixes this, so you can just
use:
CC=clang
CXX=clang++
CPP=clang-cpp
instead.
