kernel menuconfig issue related to musl

Host is amd64, glibc-based.

[smira]

yes, this seems to be a regression in main at the moment, we don't use it much, but it should be fixed anyways

[samip5]

So I think I'm understanding the error right as it's a missing ncurses (ncursesw) library?

[smira]

Yes, in the toolchain I switched ncurses to build non-wide character version, as bash needs that, it's a long story. But it doesn't affect Talos itself in any way, just the stuff around kernel.

Referring to https://github.com/siderolabs/tools/commit/0a443c6d5a1ac6764b22990be0945ef4cae8c32e?

[smira]

yes.
