Some systems (e.g. Android) define in their libc types.h
__le16, __be16, etc. Since perf is wrapping
<linux/types.h> with a local version, we need to define this
constants in the local version too.
Errors in Android:
In file included from bionic/libc/include/netinet/in.h:34:0,
from util/util.h:73,
from util/cache.h:5,
from util/abspath.c:1:
bionic/libc/kernel/common/linux/in6.h:20:2: error: unknown type name '__be16'
bionic/libc/kernel/common/linux/in6.h:21:2: error: unknown type name '__be32'
bionic/libc/kernel/common/linux/in6.h:30:2: error: unknown type name '__be16'
bionic/libc/kernel/common/linux/in6.h:31:2: error: unknown type name '__be32'
bionic/libc/kernel/common/linux/in6.h:47:2: error: unknown type name '__be32'
roundup() definition is also missing:
util/symbol.c: In function 'symbols__fixup_end':
util/symbol.c:106: warning: implicit declaration of function 'roundup'
util/symbol.c:106: warning: nested extern declaration of 'roundup'
Some macro defined in perf are also defined in libc which
leads to redefinition errors. In order to avoid these, we
guard these definitions with #ifndef.

This https://lkml.org/lkml/2012/8/29/150 should fix the netinet/in.h
build problem.
