During CI (Jenkins) build of our project we caught a strange `make` hang that's hard to understand for us. Maybe, it was something sporadic, but anyway it looked strange.

The project that was building and make hung with was u-boot (source is https://ftp.denx.de/pub/u-boot/u-boot-2020.10.tar.bz2 ) for de0-nano-soc target.

At some moment there were several "Terminated" messages (we couldn't understand where they came from), then the remaining files were built, but `make` didn't finished and left hung. The build log is attached.

I managed to connect to the hunging/running `make` process via gdb and walked several steps through the code. It looks like it
some chain of check_dep/update_file_1/update_file routings in `remake.c` code.

We just assume that there might be some bug in `make` that could lead to this `looping` instead of exit with error. And `make` developers could understand what had happened.
