I set "aarch64" to --target and make again, there are no compile errors 
this time. But no *.so are created except of some *.a in 
libunwind/src/.libs. What's more, some files, such as os-linux.c , is 
not compiled.

# ./configure --target=aarch64 --host=x86_64 CC=aarch64-linux-gnu-gcc 
LDFLAGS="-L$PWD/src/.libs"
# make
