CC util/libunwind/x86_32.o
In file included from util/libunwind/x86_32.c:33:0:
util/libunwind/../../arch/x86/util/unwind-libunwind.c: In function 'libunwind__x86_reg_id':
util/libunwind/../../arch/x86/util/unwind-libunwind.c:110:11: error: 'EINVAL' undeclared (first use in this function)
return -EINVAL;
^
util/libunwind/../../arch/x86/util/unwind-libunwind.c:110:11: note: each undeclared identifier is reported only once for each function it appears in
mv: cannot stat 'util/libunwind/.x86_32.o.tmp': No such file or directory

make[3]: *** [util] Error 2
make[2]: *** [libperf-in.o] Error 2
