[PATCH v2 0/3] update of various kbuild flags to allow usersettings

From: Sam Ravnborg

Denys Vlasenko complained that he could not set
a moduel specific linker flags on the command line.

It turned out that the cause of this was kbuild
that assigned a value to a variables that
may be modified by the user.
So any user supplied value would overwrite
the kbuild assigned value.

Fix this so we use internal variables for kbuild
feering up the official variables for use by
the user.

Changes in v2:
Fix so we can now specify both module and built-in
options on command line.
Combine all *_MODULE changes in one patch.
Add a new patch for *_KERNEL changes.
Document the new variables in makefiles.txt
Document the variables that may be set on the command line
in kbuild.txt

The frv Makefile saw a bigger cleanup this time.
I suggest to merge it through kbuild.git because the
update is dependent on the first patch in this serie.
