Suggestion: CLANG Linux host modules: Add warning and prohibit build by default if build is tried for CLANG compiled kernel.

[dreieck]

Ahoj,

as VirtualBox Linux host module does not support CLANG compiled kernels, only GCC compiled kernels, and CLANG is an officially supported compiler for the Linux kernel, and actually launching VirtualBox with host modules on a CLANG compiled kernel makes the system hard freeze,

I hereby request that the VirtualBox Linux host module build system issues a big fat warning when the modules are to be compiled for a CLANG compiled kernel and by default (without an explicit option) refuses to proceed.

References:

• Me reporting the system freeze on CLANG compiled kernel: #22064
• You saying that CLANG is not supported: #22064, comment 10

Regards!
