Description:
------------
WCOREDUMP is actually a macro on Linux and other systems, but since it was undefined at compile time the compiler implicitly defined it:

/QOpenSys/home/rpmbuild/rpmbuild/BUILD/php-7.3.1/sapi/fpm/fpm/fpm_children.c:210:28: warning: implicit declaration of function 'WCOREDUMP' [-Wimplicit-function-declaration]
    const char *have_core = WCOREDUMP(status) ? " - core dumped" : "";
                            ^~~~~~~~~

This leads to an eventual linker error due to the missing symbol:

ld: 0711-317 ERROR: Undefined symbol: .WCOREDUMP
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.

According to the Linux man page, WCOREDUMP should be gated by an #ifdef

WCOREDUMP(status)
    returns true if the child produced a core dump. This macro should only be employed if WIFSIGNALED returned true. This macro is not specified in POSIX.1-2001 and is not available on some UNIX implementations (e.g., AIX, SunOS). Only use this enclosed in #ifdef WCOREDUMP ... #endif
