I have an egdbserver port working from gdb 5.2.1 and would like to get
the multi-thread support available in 5.3.
It appears gdbserver needs the libthread_db support from glibc. I'm
using glibc 2.2.4 and only have support for static linking on my
platform. When building glibc without dynamic linking, libthread_db
doesn't get built. Any suggestions for building a static
libthread_db?

Actually yes, it's pretty easy. In the glibc source,
linuxthreads_db/Makefile:
-libthread_db-inhibit-o = $(filter-out .os,$(object-suffixes))
+#libthread_db-inhibit-o = $(filter-out .os,$(object-suffixes))
In general it's not a good idea, since you must match the libpthread
version precisely; but if you don't have dynamic linking, then this is
probably the way to go.

Also, does this require a specific kernel feature/version? It appears
to use some /proc magic. Is the /proc support available in the 2.2.20
kernel?

2.2.20 is probably fine. I haven't tried it on something that old in a
very long time though.
There's really no /proc magic involved...

Are there are any docs on the guts of how this is implemented?
