https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: sys-libs/ncurses-6.4_p20230401 has implicit function declarations in configure logs (MUSL-SYSTEM). Discovered on: amd64 (internal ref: tinderbox_musl) NOTE: (MUSL-SYSTEM) in the summary means that bug was found on a machine that runs MUSL libc but this bug MAY or MAY NOT BE related to musl. See also: https://bugs.gentoo.org/898488#c4.

After various changes upstream: - The original reported version 6.4_p20230401 (as present in the ::gentoo tree) has this issue. - The slightly more recent stable version 6.4_p20240414 (as present in the ::gentoo tree) no longer has this issue.
The ppc issue may be something else as ncurses has different CHOST matching, please report it separately if it still happens.
Especially given that the ppc issue appears to have been a compile time error rather than a configure check misfiring!
