Makefile clang-3.8:在WSL（Linux的Windows子系统）中找不到命令

我使用的是WSL（Linux的Windows子系统），版本是Ubuntu 20.04 LTS

BUILD_TOOL = \
    build_tool.o 

CC = clang-3.8

LIBS =  ../out/x64/libmbedcrypto.a

all: build_tool


build_tool: $(BUILD_TOOL)
        $(CC) $(BUILD_TOOL) $(LIBS) -o build_tool

sudo apt update
sudo apt install clang

显示错误：

clang-3.8:未找到命令

我已尝试通过apt get安装，但没有安装候选

$ sudo apt-get install clang-3.8`

在Ubuntu20.04 LTS中可用

BUILD_TOOL = \
    build_tool.o 

CC = clang-3.8

LIBS =  ../out/x64/libmbedcrypto.a

all: build_tool


build_tool: $(BUILD_TOOL)
        $(CC) $(BUILD_TOOL) $(LIBS) -o build_tool

sudo apt update
sudo apt install clang

并将Makefile重写为：

CC = clang
