Require ifunc-capable linker for i386

Description

Require ifunc-capable linker for i386

The amd64 kernel started using ifunc for a variety of functions with
arch-specific implementations, and we would like to make use of the
same functionality on i386 and as much as possible avoid divergence
between i386 and amd64. In particular, future changes for security
improvements and mitigations may rely on ifunc support.
