failure to build lib32 with boost-install.boost-install rule missing

On my Archlinux system, the package lib32-boost, which pulls the code directly from boostorg's github repo, fails to build with the following error:

ERROR: rule "boost-install.boost-install" unknown in module "Jamfile".
libs/atomic/build/Jamfile.v2:130: in modules.load

I reported the problem to the Archlinux's package maintainer, and he suggested I reported upstream as well, as all the package does is to build boost with the 32 bits flag. Complete output form the build command is [in this pastebin](https://pastebin.com/pwMKkYrEl)
