cmake's check_symbol_exists() does not forward CMAKE_REQUIRED_FLAGS to the
try_compile() it runs, unlike check_include_file() and
Internal/CheckSourceCompiles which both pass it along as
-DCOMPILE_DEFINITIONS. So the -D_GNU_SOURCE=1 that SDL adds to
CMAKE_REQUIRED_FLAGS never reaches any symbol check, and every glibc
extension hidden behind __USE_GNU is detected as missing.
HAVE_GETRESUID being unset is fatal, since SDL_gtk.c then compiles its own
static fallback which collides with the <unistd.h> declaration:
SDL_gtk.c:90:19: error: static declaration of 'getresuid' follows
non-static declaration
Pass _GNU_SOURCE via CMAKE_REQUIRED_DEFINITIONS as well. This also restores
detection of memfd_create, ppoll, posix_spawn_file_actions_addchdir,
fopen64 and fseeko64, which were silently disabled.
