mesa-dri's Makefile.common has:
USE+= compiler:c++11-lib
.if ${LLVM_DEFAULT:S,-devel,990,} >= 90
LLVM_DEFAULT= 80
.endif
.if ${ARCH} == aarch64 || ${ARCH} == amd64 || ${ARCH:Marm*} || ${ARCH} == i386 || ${ARCH:Mmips*} || ${ARCH:Mpowerpc*}
BUILD_DEPENDS+= llvm${LLVM_DEFAULT}>=3.9.0_4:devel/llvm${LLVM_DEFAULT}
.if ${COMPONENT} != libs
RUN_DEPENDS+= llvm${LLVM_DEFAULT}>=3.9.0_4:devel/llvm${LLVM_DEFAULT}
.endif
CONFIGURE_ENV+= LLVM_CONFIG=${LOCALBASE}/bin/llvm-config${LLVM_DEFAULT}
LDFLAGS+= -Wl,-rpath=${LOCALBASE}/llvm${LLVM_DEFAULT}/lib
CONFIGURE_ARGS+= --enable-llvm
.else
CONFIGURE_ARGS+= --disable-llvm
.endif
and Makefile has:
.if ${ARCH} == aarch64 || ${ARCH} == amd64 || ${ARCH:Marm*} || ${ARCH} == i386 || ${ARCH:Mmips*} || ${ARCH:Mpowerpc*}

That could be. Maybe someone from x11@ knows more.
