VclStringResourceLoader eg.
    test = smgr.createInstance("com.sun.star.resource.VclStringResourceLoader")
    invocation = test.setValue("FileName", "test")

It seems we can't cope with XInvocation implementors, so give a nice

There is no code using it anymore in the tree.

Leads to build failures on NetBSD-5.99.51 and is not needed.

It serves no useful purpose and breaks the build under some packaging
systems such as pkgsrc.

No need to mention $(LB)$/$(TARGET)$(DLLPOST) in the ALLTAR
prerequisite list. It causes errors, and is unnecessary, as pyuno.pyd
gets built anyway thanks to being the TARGET in this makefile.

No need to do the symlink if DLLPRE is empty. In that case
$(LB)$/$(TARGET)$(DLLPOST) equals $(LB)$/$(DLLPRE)$(TARGET)$(DLLPOST)
so dmake will complain about a circular dependency.

NetBSD 2.x and previous releases are long gone.

fakeroot uses LD_PRELOAD to let getuid() return 0, so getpwuid() will
not return the correct home directory. If we are under fakeroot, the
HOME environment variable can be used to do so.

Mac OS X is still being compiled vs 2.3
