Glibc is currently configured without any "--enable-kernel" option.
This causes it to use the oldest possible kernel API, slowing it down
and preventing it from using any kernel features from later versions.
Since we are likely building a kernel and matching glibc together,
backwards compatability is probably unnecessary so this patch
unconditionally configures glibc with --enable-kernel set to
BR2_TOOLCHAIN_HEADERS_AT_LEAST.
