When I build a project using vc-LTL5 with target version 5 or 6 there are still some leftover strings in the rdata-section of the binary pointing to some system dlls:

api-ms-win-core-datetime-l1-1-1
api-ms-win-core-fibers-l1-1-1
api-ms-win-core-file-l1-2-2
api-ms-win-core-localization-l1-2-1
api-ms-win-core-localization-obsolete-l1-2-0
api-ms-win-core-processthreads-l1-1-2
api-ms-win-core-string-l1-1-0
api-ms-win-core-synch-l1-2-0
api-ms-win-core-sysinfo-l1-2-1
api-ms-win-core-winrt-l1-1-0
api-ms-win-core-xstate-l2-1-0
api-ms-win-rtcore-ntuser-window-l1-1-0
api-ms-win-security-systemfunctions-l1-1-0
ext-ms-win-ntuser-dialogbox-l1-1-0
ext-ms-win-ntuser-windowstation-l1-1-0
api-ms-win-appmodel-runtime-l1-1-2

These are no direct dependencies, they are only utf16 strings in the data section occupying more than 1KB.
Using target version 10 with a dependency to ucrt, there are no such strings.

Is there a possibility to build a binary with target version 5 or 6 without these leftover strings?
