I successfully cross-compile the must-libc using clang, with the
configuration:
C=clang CFLAGS=--target=arm-none-linux-gnueabi\
--sysroot=/usr/local/arm-2009q\ -I\
/usr/local/arm-2009q3/arm-none-linux-gnueabi/libc/usr/include/ LIBCC=
./configure --target=arm
But how to force clang to use musl-libc rather than its default one? I
tried
clang --target arm-none-linux-gnueabi -nostdlib -static hello.c
~/research/musl-1.1.6/lib/crt1.o ~/research/musl-1.1.6/...

I copied everything from the lib in musl-1.1.6
to arm-2009q3/arm-none-linux-gnueabi/libc/usr/lib but there is still an
error message:
src/env/__libc_start_main.c:(.text+0x40): undefined reference to

I build the baremetal newlib using arm-none-eabi-gcc as well, but after
linking with the hello world program, it failed to run on
