[RESENT PATCH 1/1] menuconfig: GCC failing saying ncurses is not found

[Petr Vorel]

From: Petr Vorel <pvorel at suse.cz>

GCC 14 increased diagnostics levels resulting in considering the
test code to be invalid. The resulting message was misleading, saying
that ncurses was not found, while the check failed for an unrelated
reason which was hidden because GCC stderr was redirected to
/dev/null.

Hi,

Could you please accept this fix?
Originally sent July 2024 [1] (maybe even earlier). Fix is needed,
therefore used at least in Buildroot [2].

Kind regards,
Petr
