patch posix-spawn in 32bit platforms

Posix-spawn is a component of gitlabhq and gitaly, defined in RubyGems configuration file Gemfile.lock.

Recently, it has been found [1] [2] that there are some compile problems with its latest version (0.3.13), which is used in the new versions of gitlab and gitaly.

A solution [3] has been put forward, but from the answer of the original author of the project, it seems to take forever for the patch to be merged.

I have tried that by replacing posix-spawn (0.3.13) with posix-spawn (0.3.12) in file Gemfile.lock works fine on x86_32 and arm32 platforms. So, could there be a patch in the overlay that solves the problem temporarily?
