On recent make, commit 1449fb96, "arm/dt: Add a make rule to build dtb for enabled boards" breaks build of the kernel immediately:
/projects/linaro/linux-2.6/arch/arm/Makefile:292: *** mixed implicit and normal rules. Stop.
$ rpm -q make make-3.82-4.fc15.x86_64
''The previous behavior of mixing implicit and pattern rules in one line like that was never supported or documented, but due to a "hole" in the parser it worked for certain specific cases (for example, reversing that line so the pattern comes first would not work, nor would adding extra explicit targets after the pattern target).
In 3.82, the parser was tightened in this respect and that "hole" was closed, hence you see this error.''
This patch splits the rule to fix the bug.
