* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6:
modpost: support objects with more than 64k sections
trivial: fix a typo in a filename
frv: clean up arch/frv/Makefile
kbuild: allow assignment to {A,C}FLAGS_KERNEL on the command line
kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command line
Kbuild: Add option to set -femit-struct-debug-baseonly
Makefile: "make kernelrelease" should show the correct full kernel version
Makefile.build: make KBUILD_SYMTYPES work again
