Defining _GNU_SOURCE causes musl to define everything including
everything protected by _XOPEN_SOURCE. However it does not cause
musl to define _XOPEN_SOURCE.

On the other hand, the ncurses header specifically checks for
_XOPEN_SOURCE or _XOPEN_SOURCE_EXTENDED.

So it is not completely clear where this should be fixed.
