Hi,

We are currently using a modified version of the included armgcc toolchain file as our CMAKE_TOOLCHAIN_FILE:
https://doc.qt.io/QtForMCUs/qtul-cmake-toolchain-armgcc.html

We would like to know why some of the GCC compiler flags are used. Specifically,
-ffreestanding
-fno-builtin

@wcampbell-ara I suggest to ask this on Qt developers mailing list as this is user forum.
