I suspect it's somehow related to this (from libcompiler_rt/Makefile):

# Don't build clear_cache on ARM with clang as it is a builtin there.
.if ${MACHINE_CPUARCH} != "arm" || ${COMPILER_TYPE} != "clang"
SRCF+=  clear_cache
.endif

Do you know what code in ctypes for Python is referring to
that symbol?   There may be some oddity in how that symbol is
being referenced that's incompatible with the clang built-in.
