-4.6 Using hostprogs-$(CONFIG_FOO)
----------------------------------
-
-	A typical pattern in a Kbuild file looks like this:
-
-	Example::
-
-		#scripts/Makefile
-		hostprogs-$(CONFIG_KALLSYMS) += kallsyms
-
-	Kbuild knows about both 'y' for built-in and 'm' for module.
-	So if a config symbol evaluates to 'm', kbuild will still build
-	the binary. In other words, Kbuild handles hostprogs-m exactly
-	like hostprogs-y. But only hostprogs-y is recommended to be used
-	when no CONFIG symbols are involved.

 5 Kbuild clean infrastructure
 =============================
 
 "make clean" deletes most generated files in the obj tree where the kernel
 is compiled. This includes generated files such as host programs.
-Kbuild knows targets listed in $(hostprogs-y), $(hostprogs-m), $(always),
-$(extra-y) and $(targets). They are all deleted during "make clean".
-Files matching the patterns "*.[oas]", "*.ko", plus some additional files
-generated by kbuild are deleted all over the kernel src tree when
-"make clean" is executed.
