Mike Kaganski 3fc2c054c5 Fix build in a specific VS2022 environment
Building Executable_odbcconfig using VS2022 failed for me reproducibly
for some time, with

  mt.exe : general error c101008d: Failed to write the updated manifest to the resource of file "C:/lo/src/build/instdir/program/odbcconfig.exe". The file or directory is corrupted and unreadable.
  make[1]: *** [C:/lo/src/core/dbaccess/Executable_odbcconfig.mk:10: C:/lo/src/build/instdir/program/odbcconfig.exe] Error 139

It is caused by linking odbccp32, and legacy_stdio_definitions required
by the latter with current versions of UCRT.

It seems to work OK for others; but being unable to find what's different
on my system, I have this workaround, using run-time loading instead.
