Re: [PATCH edk2-staging 01/19] IntelOpenSourceUndiPkg.dsc: add AARCH64 and ARM to supported architectures

[Ryszard Knop <ryszard.knop@linux.intel.com>]

One thing of note here: We're primarily using MSVC for IA32/X64 builds,
and that's the only thing we "officially" support. I'll try to build
and test GCC binaries once in a while as well, but things might break
once now and then. Our team also doesn't have any ARM hardware to test
this on, so I'd appreciate any reports if it breaks :)
