Paul Menzel 9feeb638cd tools build: fix # escaping in .cmd files for future Make 
In 2016 GNU Make made a backwards incompatible change to the way '#'
characters were handled in Makefiles when used inside functions or
macros:

http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57

Due to this change, when attempting to run `make prepare' I get a
spurious make syntax error:

    /home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator.  Stop.

When inspecting `.fixdep.o.cmd' it includes two lines which use
unescaped comment characters at the top:

    \# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep)
    \# using basic dep data

This is because `tools/build/Build.include' prints these '\#'
characters:

    printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \
    printf '\# using basic dep data\n\n' >> $(dot-target).cmd;           \

This completes commit 9564a8cf42 ("Kbuild: fix # escaping in .cmd files
for future Make").
