No, espressif does not provide FreeBSD versions of their toolchains.

And yes, that is helpful; looking at tools/tools.json for 5.3.1 I see 
it's still using 13.2.0_20240530 so I focus on that version.

Here's some info about what I'm upgrading from:

    https://www.freshports.org/devel/xtensa-esp32-elf/

It is a lot of work to make this guy build within the FreeBSD ports 
system, I have to identify and pre-download all of the source blobs 
prior to the build because ports aren't allowed to use the network 
during the build... (And it doesn't help that bootstrapping a cross 
compiler takes a long time.)
