Why are you using this strange invocation of the linker?  If I run
"cc -v -o z z.c", here is how it invokes ld:

  "/usr/bin/ld" --eh-frame-hdr -dynamic-linker /libexec/ld-elf.so.1 
--hash-style=both --enable-new-dtags -o z /usr/lib/crt1.o 
/usr/lib/crti.o /usr/lib/crtbegin.o -L/usr/lib /tmp/z-9530c3.o -lgcc 
--as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s 
--no-as-needed /usr/lib/crtend.o /usr/lib/crtn.o

The resulting program runs without difficulty.          -- George
