ncurses: convert libncursesw.a into a static ldscript

[bapt]

Summary

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

[olivier]

Does it mean that from an updated FreeBSD main-n249987-b158d4d7a12 (commit at "rescue: fix after with to a ldscript of libncursesw.a"), I should be able to build those few weeks old nanobsd ?
Or should I patch those old weeks sources with this patch?

Because I still have the problem trying to build from an updated current:

# uname -a

(etc..)
