Description Dmitry Torokhov 2019-12-11 20:02:00 UTC 
efivar package is using the same compiler options for both the host and the target, and it may cause build fail with "invalid instruction" when hosts architecture is sufficiently different from the target (even though both are x86).

We need to import patch that forces to use hosts' microarchitecture when compiling parts of the build utilities that are running on host.

Reproducible: Always
