Follow-up Comment #2:

This is discussed in the NEWS file for GNU make 4.3:


* 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:
    H := \#
    foo := $(shell echo '$H')
  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.
