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 9564a8cf422d ("Kbuild: fix # escaping in .cmd files
for future Make").
