The generated library does indeed contain all systems that your library
contains on. The undefined references are init functions, which need to
be called via ecl_init_module after cl_boot to initialize the compiled
libraries (see
https://common-lisp.net/project/ecl/static/manual/System-building.html#Build-it-as-shared-library-and-use-in-C
for more details).

Since you didn't specify an explicit init name yourself, init functions
are automatically generated for each system contained in the final
library. When compiling a monolithic library, it is preferable to
specify an explicit init name yourself, for example as

(asdf:make-build :embedded-console :type :static-library :move-here
#P"/my/output/dir" :monolithic t :init-name "init_lib_embedded_console")

and then invoke it using

extern void init_lib_embedded_console(cl_object);
/* ... */
cl_boot(argc, argv);
ecl_init_module(NULL, init_lib_embedded_console);
