[PATCH 0/1] MR6992: configure: Define _load_config_used symbol in the cross-compiler test program.

[Jacek Caban (＠jacek)]

The load configuration is mandatory for ARM64EC binaries, and the MSVC linker emits a warning when it is missing. It makes sense, so I plan to add a similar warning to lld-link. Since the configure scripts treat linker warnings as errors, defining the load configuration ensures future compatibility.
