I don't follow you here.
gcc112 is a ppc64le machine, and I'm cross-compiling for ARM.
Is it possible for those x86 .dll provided by monolite to be used on a
ppc64le machine ?

The ppc64le machine that causes the failure has 256GB of RAM.

It's just:
BR2_arm=y
BR2_PACKAGE_MONO=y
But you won't be able to reproduce the problem on your PC, because your
PC is x86-64, and the build failure seems to be specific to building on
ppc64le.
Do you have an account on the gcc compile farm ?
Best regards,
Thomas
