Subject: [PATCH] Makefile: allow debug info to be specified

Add variable `DEBUG' that can be used to specify debug flags for the Go
tool when building either the client or the lxd.

For example:

 $ DEBUG='-gcflags "-N -l"' make

The -N flag enables debug information and -l disables compiler inlining.
Example of how to debug using lldb can be found here:
