Strange... it works for me.  Maybe try reading the docs for llvm-link?

$ llvm-as -o m1.bc

define i32 @main() {
entry:
%tmp0 = call i32 @MyOwnFunction()
 ret i32 0
 }
 declare i32 @MyOwnFunction()

$ llvm-as -o MyOwnFunction.bc

;ModuleID = 'MyOwnFunction'
define i32 @MyOwnFunction() {
entry:
 ret i32 55
 }

$ llvm-link m1.bc MyOwnFunction.bc -o - | lli
$
