Yonghong fixed llvm bug with big-endian dwarf [1]
and binutils worked out of the box :)

$ ./bin/clang -O2 -target bpfeb -c -g test.c
$ /w/binutils-gdb/bld/binutils/objdump -S test.o

test.o:     file format elf64-bpfbe

Disassembly of section .text:
0000000000000000 <bpf_prog1>:
int bpf_prog1(void *ign)
{
  volatile unsigned long t = 0x8983984739ull;
