d26c1ba4de CMake: Make sure the strip_for_binary project works with Makefiles
The printed lib path did not appear when building the project with the
Unix Makefiles generator.

Make sure the printing does not depend on the shell used by the
generator, by making it VERBATIM.

39f657032b CMake: Generate and use a wrapper script for stripping binaries
MinGW 11.2.0 comes with a strip.exe that strips the ".gnu_debuglink"
section in binaries, a section that is needed for the separate debug
information feature.

binutils version 2.34 mentions the feature for the first time:
https://sourceware.org/binutils/docs-2.34/binutils/strip.html#strip

To ensure the debuglink section is preserved, generate a shell wrapper
that calls the original strip binary with an extra option to keep the
required section.

To determine if the option is supported, we build a real shared library
on which strip will be called with the --keep-section option.
If the option is not supported, a wrapper is not generated and the
stock strip binary is used.

This logic only applies when targeting Linux and MinGW + a shared
library Qt. For other targets, the stock strip binary is used.

Developers can opt out of this logic by passing
-DQT_NO_STRIP_WRAPPER=TRUE when configuring each Qt repo.
