We're passing -Oz for release builds, but that's not a flag the linker
understands when -ltcg is enabled. The build fails with:
ld.gold: fatal error: Optimization level must be between 0 and 3
Fix this by using -O2, which -Oz is based on, and -O3 for the "full
optimization" that is used for core and gui.
Pick-to: 6.2
Fixes: QTBUG-89472
