ncurses: convert libncursesw.a into a static ldscript

Browse source 
Introduce the notion of static linker scripts to allow libncursesw.a to
track its dependency on libtinfow.a

this allows the build of older freebsd source tree to happen and make
static linking in part with dynamic linking which already provides a
ldscript

This fixes a bootstrapping FreeBSD 12 or 13 on recent FreeBSD 14
