Please also attach emerge --info output, and config.log

Can you attach make.conf as well? The fact that it's configuring in a "cross" dir rather than "ncurses-6.1-abi_x86_64.amd64" makes me suspect some environment variable pollution.

x86_64-pc-linux-gnu-gcc: error: unrecognized command line option '--malign-data=abi'; did you mean '-malign-data=abi'?
I was aware of it and rectified it and ran again emerge --ask --verbose --update --deep --newuse @world
Which should have sorted it but it did not. Just cleaned all drives and restart fresh and the issue is still present however.

emerge -vauDN @world appears to be rebuilding packages only when the user changes the USE_FLAG but not the COMMON_FLAGS...
That learned then used emerge -ve for rebuilding...
...and selectively removed COMMON_FLAGS. It would that -masm=intel is causing the issue, which is curious though since other packages compiled just fine with the flag in place. Having removed -masm=intel the package then compiled.

So this config.log is obsolete because it's about the incorrect `--malign-data=abi`.
