请大家帮我看看是怎么回事：
我用的是ARM在Linux下编写C语言程序，名为pthread.c和Makefile
但是make之后产生不了可执行的文件，如下：
[root@localhost 02_pthread]# ls
Makefile pthread.c
[root@localhost 02_pthread]# make clean
rm -f ../bin/pthread ./pthread *.elf *.gdb *.o
[root@localhost 02_pthread]# make
armv41-unknown-linux-gcc -c -o pthread.o pthread.c
make: armv41-unknown-linux-gcc: Command not found
make: *** [pthread.o] Error 127
[root@localhost 02_pthread]# ls
Makefile pthread.c
请各位高手帮帮我，谢啦！
