Indeed.

> It looks like the only way I'll be able to get CLOCK_MONOTONIC is by compiling the glibc for *arm* with nptl instead of linuxthreads, but looking at the crosstool matrix it doesn't look like it builds. I may have to rethink the timers I'm using.

Correct. With the version of the tools you have NPTL support for  ARM
is  not possible yet. It will be supported in ELDK 4.2 for ARM (to be
released later this year).
