[Buildroot] [PATCH 1/1] Fix ncurses gcc-5.0 compile issue (for real)

[kyak]

The previous patch didn't work in all cases. The new patch is taken from
upstream:

-Fix GCC 5.x preprocessor failure
-
-Building ncurses 5.9 with GCC 5.x fails with a syntax error, caused by
-earlier preprocessing. This failure is more likely when building for
-host (e.g. host-ncurses) that recently updated to GCC 5.x.
-
-This patch is taken from the following link (more information is also
-available here):
