I think the cleanest solution would be to remove -Dstatic=.  I don't
know the exact reason for it being there.  The best reference I found is

Russell, maybe these toolchain problems are gone in the meantime?  Some
time ago I tried removing that and the decompressor was still
functional---which doesn't mean it's save in all situations with all
toolchains.

Best regards
Uwe
