--- Comment #1 from Dimitry Andric <d...@freebsd.org> ---
lib/Makefile has:
# The libraries under libclang_rt can only be built by clang, and only make
# sense to build when clang is enabled at all. Furthermore, they can only be
# built for certain architectures.
.if ${MK_CLANG} != "no" && ${COMPILER_TYPE} == "clang" && \
(${MACHINE_CPUARCH} == "aarch64" || ${MACHINE_CPUARCH} == "amd64" || \
${MACHINE_CPUARCH} == "arm" || ${MACHINE_CPUARCH} == "i386" || \
${MACHINE_CPUARCH} == "powerpc")
_libclang_rt= libclang_rt
.endif
while the top-level Makefile.inc1 has:
native-xtools: .PHONY
${_+_}cd ${.CURDIR}; ${NXBTMAKE} _cleanobj
# Build the bootstrap/host/cross tools that produce native binaries
${_+_}cd ${.CURDIR}; ${NXBTMAKE} kernel-toolchain
# Populate includes/libraries sysroot that produce native binaries.
# This is split out from 'toolchain' above mostly so that target LLVM
# libraries have a proper LLVM_DEFAULT_TARGET_TRIPLE without
# polluting the cross-compiler build. The LLVM/GCC libs are skipped
# here to avoid the problem but are kept in 'toolchain' so that
# needed build tools are built.
${_+_}cd ${.CURDIR}; ${NXBTMAKE} _includes MK_CLANG=no
${_+_}cd ${.CURDIR}; ${NXBTMAKE} _libraries MK_CLANG=no
[...]
It looks like the MK_CLANG=no was added on purpose, precisely to avoid
populating the lib/clang/x.y.z directory. I do not fully understand the
reasoning mentioned in the comment about "avoiding the problem".
Bryan added this part in base r325001, so maybe he can shed some light.
