Look at your "LIBS" right here.
-L <= adds the path for the linker
-l <= adds the library itself to tell the linker to link it

Since the linker doesn't know which library to link with, none of these
functions (Perl_sys_term & others) are defined at link time. I'm not
sure what's the name of your library should be, but something like this
might work better:

LIBS += -LC:/Perl/lib/CORE \
		-lperlcore


this is *IF* the library is called "perlcore"
