criu/log.c:391:2: error: called object type 'int' is not a function or function pointer
errno = __errno;
^~~~~
/root/android-ndk/toolchains/llvm/prebuilt/linux-x86_64//sysroot/usr/include/errno.h:43:24: note: expanded from macro 'errno'
in Android NDK's errno.h:
42: int* __errno(void) __attribute_const__;
43: #define errno (*__errno())
so rename __errno to _errno to pass build
