Link step: Enable to configure deduplication of libraries
Some platforms, Apple or Windows for instance, do not require to duplicate
static libraries to resolve mutual dependencies. Moreover, Xcode version 15
emits a warning if a library is duplicated.
On Windows, enable a better control of libraries order.
Fixes: #20722, #25297
