Subject: Compiler/TI: Restore response file usage for linker

The commit 98fea8205e (Compiler/TI: Avoid response file usage for
linker, 2020-07-11, v3.19.0-rc1~495^2) disabled linker file usage by
default.  The previous settings were working, even if not for all cases.
Restore them and add an explanation in a comment.

Issue: #22233
