[PATCH] configure: fix build on noMMU uclinuc targets

[Yann E. MORIN]

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 build.

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

Fixes:
