Building lrzsz with this defconfig works:

BR2_GCC_VERSION_13_X=y
BR2_PACKAGE_LRZSZ=y

and gets broken when switched to gcc 14:

BR2_PACKAGE_LRZSZ=y

Subject: [PATCH] configure: fix for gcc >= 14.x
The pre-generated configure script has a check that doesn't work with
GCC >= 14.x:
configure:1932: checking for ANSI C header files
configure:1945: /home/bernd/buildroot/output/per-package/lrzsz/host/bin/i586-buildroot-linux-gnu-cpp -D_LARGEFILE_SOURCE -D_LARGEFILE64_S
OURCE -D_FILE_OFFSET_BITS=64 conftest.c >/dev/null 2>conftest.out
configure:2012: /home/bernd/buildroot/output/per-package/lrzsz/host/bin/i586-buildroot-linux-gnu-gcc -o conftest -D_LARGEFILE_SOURCE -D_L
ARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -g0 -D_FORTIFY_SOURCE=1 -std=gnu17 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BIT
S=64 conftest.c 1>&5
configure: In function 'main':
configure:2007:67: error: implicit declaration of function 'exit' [-Wimplicit-function-declaration]
2007 | if (XOR (islower (i), ISLOWER (i)) || toupper (i) != TOUPPER (i)) exit(2);
| ^~~~
configure:2003:1: note: include '<stdlib.h>' or provide a declaration of 'exit'
2002 | #include <ctype.h>
+++ |+#include <stdlib.h>
Doing AUTORECONF = YES doesn't work as the configure.in is very old, so
let's fix the configure script directly.
