Still doesnt work here (on a 32-bit/32-bit system, F11) - i've applied 
your debug patch and added V=2:

 earth4:~/tip/tools/perf> make -s -j LDFLAGS=-static NO_64BIT=yes V=2
 /usr/bin/ld: cannot find -lpthread
 collect2: ld returned 1 exit status
 Makefile:493: *** No libelf.h/libelf found, please install 
 libelf-dev/elfutils-libelf-devel and glibc-dev[el].  Stop.

Sure, we could do that - mind sending a patch for that?
