Subject: [PATCH] fix cc-option-yn whitespace

This change:

	commit 5de043f4bd11a9e0a3e8daec7d1905da575a76b7

	    [PATCH] kbuild: improve option checking, Kbuild.include cleanup

introduced leading whitespace in the results of cc-option-yn and such.
This breaks some of their uses, like HAS_MTUNE in arch/i386/Makefile.cpu.

This patch fixes the regression.
