[klibc] [PATCH] build: Define __EXPORTED_HEADER__

[Mike Waychison]

The kernel header guard to ensure that headers aren't included from
userland moved in commit 69c8f52b.  This causes the following message to
be emitted when building klibc (which is designed to use kernel headers
explicitly):

/usr/local/src/git/linux-2.6//include/linux/types.h:13:2: warning: #warning "Attempt to use kernel headers from user space, see http://kernelnewbies.org/KernelHeaders"

In order to silence this warning, make sure we define
__EXPORTED_HEADERS__ when building klibc userland.
