+Subject: Kbuild: fix # escaping in .cmd files for future Make
+MIME-Version: 1.0

+
+commit 9564a8cf422d7b58f6e857e3546d346fa970191e upstream.
+
+I tried building using a freshly built Make (4.2.1-69-g8a731d1), but
+already the objtool build broke with
+
+orc_dump.c: In function ‘orc_dump’:
+orc_dump.c:106:2: error: ‘elf_getshnum’ is deprecated [-Werror=deprecated-declarations]
+  if (elf_getshdrnum(elf, &nr_sections)) {
+
+Turns out that with that new Make, the backslash was not removed, so cpp
+didn't see a #include directive, grep found nothing, and
+-DLIBELF_USE_DEPRECATED was wrongly put in CFLAGS.
+
+Now, that new Make behaviour is documented in their NEWS file:
+
+  * WARNING: Backward-incompatibility!
+    Number signs (#) appearing inside a macro reference or function invocation
+    no longer introduce comments and should not be escaped with backslashes:
+    thus a call such as:
+      foo := $(shell echo '#')
+    is legal.  Previously the number sign needed to be escaped, for example:
+      foo := $(shell echo '\#')
+    Now this latter will resolve to "\#".  If you want to write makefiles
+    portable to both versions, assign the number sign to a variable:
+      C := \#
+      foo := $(shell echo '$C')
+    This was claimed to be fixed in 3.81, but wasn't, for some reason.
+    To detect this change search for 'nocomment' in the .FEATURES variable.
+
+This also fixes up the two make-cmd instances to replace # with $(pound)
+rather than with \#. There might very well be other places that need
+similar fixup in preparation for whatever future Make release contains
+the above change, but at least this builds an x86_64 defconfig with the
+new make.
