Are you sure this is all that's required?

Runtime tested eglibc and klibc on Zaurus collie. Same binaries even tested on armv5te.

It's not up to the build environment to provide --fix-v4bx to the kernel makefiles to work around this problem. That's just the sticky plaster fix and not proper engineering.

This updates the h3600 defconfig against the latest kernel with some small options coming and going due to Kconfig structure, then modernize it to: - Use EABI to compile the kernel - Configure for low latency preemptive kernel - Configure for tickless idle - Enable HRtimers Tested on the iPAQ h3630.
