* [Buildroot] [PATCH v2] arch/x86: remove support for i386

  To: buildroot

The Linux kernel doesn't even support i386 anymore, there is no NPTL
support for i386 and uClibc-ng only supports NPTL on x86, so there is
essentially no usable thread implementation. Most likely glibc and
musl also don't support i386 either. So it's time to remove the
support for this architecture variant.

Changes since v1:
 - Add Config.in.legacy entry, as suggested by Arnout.
 - Remove i386 reference in qemu.mk, as noticed by Arnout.
