db1806edcf perf tools: Fix statfs.f_type data type mismatch build error with uclibc 
ARC Linux uses the no legacy syscalls abi and corresponding uClibc headers
statfs defines f_type to be U32 which causes perf build breakage

http://git.uclibc.org/uClibc/tree/libc/sysdeps/linux/common-generic/bits/statfs.h
