Build process is broken in Platform.cpp: sys/sysctl.h: No such file or directory with glibc 2.32.x

I tried to build from git imagewriter, but build process is broken while processing Platform.cpp:

g++ -c -pipe -D_FORTIFY_SOURCE=2 -march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fvisibility=hidden -fvisibility-inlines-hidden -std=gnu++11 -Wall -Wextra -D_REENTRANT -fPIC -DUSEUDISKS2 -DAPP_VERSION=\"1.10\" -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_DBUS_LIB -DQT_CORE_LIB -I. -I. -I/usr/include/qt -I/usr/include/qt/QtWidgets -I/usr/include/qt/QtGui -I/usr/include/qt/QtDBus -I/usr/include/qt/QtCore -I. -I/usr/lib/qt/mkspecs/linux-g++ -o Platform.o Platform.cpp
MainWindow.cpp:40:10: fatal error: sys/sysctl.h: No such file or directory
   40 | #include <sys/sysctl.h>
      |          ^~~~~~~~~~~~~~
compilation terminated.

It looks like to be related to glibc which removed sys/sysctl.h back in April 2020:

https://sourceware.org/git/?p=glibc.git;a=commit;h=076f09afbac1aa57756faa7a8feadb7936a724e4

So any glibc version starting with 2.32 is breaking build process.
