[DRE-maint] Bug#1012247: ruby3.1: Please build with --with-coroutine=ucontext on x32

[John Paul Adrian Glaubitz]

Source: ruby3.1
Version: 3.1.2-1
Severity: normal
Tags: patch

Hello!

ruby3.1 FTBFS on x32 because the configure misdetects x32 as amd64:

checking stack growing direction on x86_64... -1
checking native coroutine implementation for x86_64-linux-gnux32... 
configure: error: '' is not supported as coroutine
make[1]: *** [debian/rules:91: override_dh_auto_configure] Error 1
make[1]: Leaving directory '/<<PKGBUILDDIR>>'

This can be fixed by building ruby3.1 on x32 with "--with-coroutine=ucontext".

Can you apply the attached patch?
