[PATCH v3 1/2] ntdll: Allow loading system DLLs from a path specified at configure time.
Many distributions provide MinGW-compiled system DLLs which are currently bundled with Wine. Unfortunately, while MinGW pkg-config can be used to detect the linking path, there is no standardized runtime path, and many distributions in fact use different paths.
Signed-off-by: Zebediah Figura zfigura@codeweavers.com --- v3: Use AC_ARG_WITH instead of AC_ARG_VAR, and pass the path via the top-level makefile rather than config.h.

That is, load Wine system dependencies only when they are imported from Wine builtins or other system dependencies, and do not match a Wine system dependency by its base name when looking for already-loaded modules.
The reasoning is that it is possible for an application to ship, and expect to use, a newer version of a MinGW-compiled library, or one with custom patches, or possibly an unrelated library with the same name. We don't want to offer Wine's system dependencies in place of the application's, or vice versa.
