Add back a simplified version of the loader static address tables.

If not taking the symbol addresses, linkage will break badly, as not
all symbols will be present, and it also requires changing library order,
and/or making some changes like the "libosandcommon".

  This table should be modified to be generated automatically, as
it is required to "fool" the compiler/loader into adding all required
symbols to the X Server.
