+ - Verbose kernel compile/build output:
+
+ Normally the kernel build system runs in a fairly quiet mode (but not
+ totally silent). However, sometimes you or other kernel developers need
+ to see compile, link, or other commands exactly as they are executed.
+ For this, use "verbose" build mode. This is done by inserting
+ "V=1" in the "make" command. E.g.:
+
+ make V=1 all
+
+ To have the build system also tell the reason for the rebuild of each
+ target, use "V=2". The default is "V=0".
