[Gm2] compiler complains about missing object file wich is inside a library archive

[Martin Kalbfuß]

Hi,

I try to compile a program with

gm2 -c -fiso -I../def -I../src test.mod
gm2 -o test test.mod -L../src -lsk -lSDL  

It complains about the missing file SKVideo.o.

cannot find SKVideo.o or SKVideo.a

The definition module SKVideo.def is in ../def. The implementation
module is inside libsk.a. lisk.a is in ../src.
Either I forgot to set a required option, or it isn't possible to link
modules inside static libs.
