package/ncurses: fix build on noMMU uclinux targets

Browse source 
The ncurses buildsystem does not recognise 'uclinux' as being a 'linux',
so it falls back to generic checks, especially when trying to decide
what macros to define. So it misses defining absolutely required macros
when doing widechar, which break the bui,d.

But 'uclinux' is just a 'linux' like any other in this respect.

We fix both aclocal.m4 and the generated ./configure script because
ncurses does not autoreconf correctly (see comment in 0001-*.patch).

Fixes:
