Before this fix, running configure on Solaris 11.4 x86 with gcc 14
claimed x86 systems were big endian, because the test failed to compile:
conftest.c:103:1: error: return type defaults to 'int' [-Wimplicit-int]
103 | main () {
| ^~~~
conftest.c: In function 'main':
conftest.c:111:15: error: implicit declaration of function 'exit'
[-Wimplicit-function-declaration]
111 | exit (u.c[sizeof (long) - 1] == 1);
| ^~~~
