To me it looks like the Makefile has some errors, or my make behaves strangely

I think the Makefile error is that make doesn't expand $@ in line 20
/*
  EXTRA_CFLAGS += -g -Wa,-adhlms=$@.lst -fno-omit-frame-pointer
*/
as it flooded me with info. i saved the stderr, and realised this:
/*
{standard input}: Assembler messages:
{standard input}:45564: Warning: can't open .lst: Permission denied
...

although, the uber dirty trick to change the line to 
/*
  CFLAGS += -g -Wa,-adhlms=$@.lst -fno-omit-frame-pointer
*/
did the trick. ;) I recommend examining this error as well, (I'm not a makefile master, it'd take ages for me to find the cause and the fix) but if I see the situation wee for the first glimpse this as well may be some linux kernel makefile related stuff.

Thank you, this is good news for me! I hope soon I'll be running nilfs2!

Sorry for the long letter, hope I could help, and I'm waiting for the news.
