Not sure (https://software.intel.com/content/www/us/en/develop/documentation/cpp-compiler-developer-guide-and-reference/top/compiler-reference/compiler-options/compiler-option-details/advanced-optimization-options/ffreestanding-qfreestanding.html)
But it seems like in this article (https://nullprogram.com/blog/2016/01/31/) -ffreestanding is available on MinGW so maybe that's where we'd have to build llvmlibc to ensure the freestanding environment?
