This one leads to the following compile failure for qt5webengine-5.15.2:

  .../host/lib/gcc/arm-buildroot-linux-gnueabihf/10.3.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: cannot find crti.o: No such file or directory
collect2: error: ld returned 1 exit status


But the file crti.o exists:

	$ find . -name crti.o
	./build/glibc-2.34-9-g9acab0bba6a5a57323b1f94bf95b21618a9e5aa4/build/csu/crti.o
	./host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/crti.o


Did not (yet) test with your latest (v2) patch iteration...

Compile with qt5webengine bump to 5.15.8-lts fails already before the linking stage
(see secoidt.h/pk11pub.h No such file or directory failure reported by already by
Thomas)...
