I make a test with small program and it's a option " -shared" only into
CGO_LDFLAGS which causes me problem.
If I don't use it of course I can't use dynamic libs. Do you think the
libstd.so program?
ron:~/test_go$ ldd ./test_go
linux-vdso.so.1 (0x0000007f87ebc000)
libstd.so => /home/ron/go-1.5/pkg/linux_arm64_dynlink/libstd.so
(0x0000007f857e9000)
libdl.so.2 => /lib/aarch64-linux-gnu/libdl.so.2 (0x0000007f857c0000)
libpthread.so.0 => /lib/aarch64-linux-gnu/libpthread.so.0
(0x0000007f85790000)
libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000007f8561d000)
/lib/ld-linux-aarch64.so.1 (0x0000007f87e8c000)
