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?
