ncurses detection not working on macOS 14

[berquist]

Caused by #1052.

The system-provided ncurses5.4-config produces some garbage paths. I see this on 14.4 (Xcode 15):

$ which ncurses5.4-config
/usr/bin/ncurses5.4-config
ncurses5.4-config --libs
-L/usr/local/lib -lncursesw
$ ncurses5.4-config --cflags
-D_DARWIN_C_SOURCE -I/usr/local/include/ncursesw -I/usr/local/include
$ ls /usr/lib/*curses*
zsh: no matches found: /usr/lib/*curses*
$ find /usr -type f -name "*curses*" 2>/dev/null | sort
/usr/bin/ncurses5.4-config
/usr/lib/zsh/5.9/zsh/curses.so
/usr/share/man/man1/adacurses-config.1
/usr/share/man/man1/adacurses.1
/usr/share/man/man1/ncurses5-config.1
/usr/share/man/man1/ncurses5.4-config.1
/usr/share/man/man1/ncursesw5.4-config.1
/usr/share/zsh/5.9/functions/tetriscurses

and this on 13.5 (Xcode 14):

$ ncurses5.4-config --libs
-lncurses
$ ncurses5.4-config --cflags
-I/usr/include/ncurses

configure doesn't fail in either case:

checking for ncurses6-config... no
checking for ncurses5.4-config... /usr/bin/ncurses5.4-config
checking for ncurses.h... yes
checking for curses library... yes

but the actual build passes with Xcode 14 and fails with Xcode 15. This must mean that libncurses is actually somewhere on that machine.

find $(xcode-select -p) -name "*curses*" 2>/dev/null | sort on Xcode 14:
