Let me know when and how and I'll update the build machines.

I've now committed HW watchpoint support to mainline GDB, and backported to Linaro GDB 7.2 (rev. 32992).
Before you update the build machines, please make sure that the hardware/kernel on those machines actually support HW watchpoints. The simplest way to find out is to verify that the kernel boot messages include something like:
hw-breakpoint: found 6 breakpoint and 1 watchpoint registers.

Ah. My main build machines are OMAP3s. I'll see about updating the Pandas and using them for GDB builds.
