In share/mk/bsd.own.mk, modify these parts:

# Clang is only for x86, powerpc and little-endian arm right now, by default.
.if ${__T} == "amd64" || ${__T} == "i386" || ${__T:Mpowerpc*}
__DEFAULT_YES_OPTIONS+=CLANG CLANG_FULL
.elif ${__T} == "arm" || ${__T} == "armv6"
__DEFAULT_YES_OPTIONS+=CLANG
# GCC is unable to build the full clang on arm, disable it by default.
__DEFAULT_NO_OPTIONS+=CLANG_FULL
.else
__DEFAULT_NO_OPTIONS+=CLANG CLANG_FULL
.endif
# Clang the default system compiler only on little-endian arm and x86.
.if ${__T} == "amd64" || ${__T} == "arm" || ${__T} == "armv6" || \
    ${__T} == "i386"
__DEFAULT_YES_OPTIONS+=CLANG_IS_CC
.else
__DEFAULT_NO_OPTIONS+=CLANG_IS_CC
.endif

The first part enables building clang, the second makes it the default
compiler.  I take it you only want the first one for now?
