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.
