Subject: [PATCH 17/39] kbuild: fix header export when __ASSEMBLY__ is used

unifdef got confused by:

Because it does not know __ASSEMBLY__ it does not
detect that htis is not for userspace.
This caused too much code to be exported, and headers_check barfed
over this code.

For arm this fixes following "make headers_check" warning:
/usr/include/asm/hwcap.h:29: extern's make no sense in userspace

Russell King suggested to undefine __ASSEMBLY__ to fix this warning.
