Finally!

I partially solved the mystery why I can't build trinity in an actual environment but can in a virtual environment.

The problem was caused by the environment variable BASH_ENV. Beats me why this caused the build script to falter or generated that strange message about ldd and conftest.out.

Removing the environment variable from my global /etc/bashrc solved the problem.

For root the variable was set to /root/.bashrc.

Now I can build with either rebooting or using that same partition in a chroot environment.

The cause is repeatable and certain. Add the variable and trinity won't build. Specifically arts. Remove the variable and arts builds.

The greater mystery is why that same variable being set in the virtual machine did not cause the same build problem. I'm happy the cause is solved but the reason remains a mystery. If anybody has a clue please share.

Building arts took about 4 minutes in the physical machine and about 14 minutes in the VM.

The $HOME/.bashrc file sourced /etc/bashrc. I wonder whether there is a bug in the make process that gets confused about the BASH_ENV variable. Perhaps some kind of second sourcing of /etc/bashrc by sourcing $HOME/.bashrc set by the BASH_ENV variable and causing some kind of recursive effect that deleted another variable that tripped the build process.
