Please share the build.log from the crosstool-NG directory.

Attached build.log, config.log and, .config files in zip as I ran make again in a fresh installation.

[ALL ] /mnt/d/Embedded/esp-open-sdk/crosstool-NG/.build/src/isl-0.14/missing: line 81: automake-1.14: command not found
[ALL ] WARNING: 'automake-1.14' is missing on your system.

I'd say 'just do the obvious'...

[siriuspal]

Automake 1.15 is installed and recognized. Is version 1.14 a requirement?

automake --version

automake (GNU automake) 1.15

Installed automake-1.14 from source. That eliminated the error.
Ubuntu 16.04 does not have automake-1.14 in apt repository.
Request including support for newer versions of automake.

[jcmvbkbc]

Automake 1.15 is installed and recognized. Is version 1.14 a requirement?

Well, AFAIK automake shouldn't be invoked at all unless parts of the project build system are changed. It's definitely not called for ISL in the builds that I run.

I was doing a fresh build of the toolchain itself.
