This explanation is a bit weird, you clearly don't need to create a
defconfig to reproduce the problem. You simply need to create any
configuration that has google-breakpad enabled.

This is not the point. The point is that this linux_syscall_support.h
file is installed by a dependency of google-breakpad, and dependencies
are not guaranteed to be available before the configure step of the
package.

I've applied to master after adjusting the commit log.

Thanks!
