CHK libelf CHK libdw CHK libunwind CHK -DLIBELF_MMAP /tmp/ccYJwdR0.o: In function `main': :(.text+0x18): undefined reference to `elf_begin' collect2: error: ld returned 1 exit status This cannot happen since we checked the elf_begin() when checking libelf and it succeeded. Fix it by using a same flag with libelf checking.
