Details:

The attached Makefile demonstrates a failure to filter the "$" character from
a string using subst function. The attached Makefile.patch includes a
workaround to this problem withthe insertion of a single space in the string
to be filtered. This Makefile logic works as expected for GNU Make version 4.0
and older on various OSes and machine architectures (RHEL7, MacOSX, TOSS,
x86_64, powerpc etc.):

--- BEGIN correct output ---
Makefile:2: CVS_BASE_TAG_NAME = v1.1.1beta.1
CVS_BASE_TAG_NAME = v1.1.1beta.1
----
make --version

--- END correct output ---


Unfortunately, GNU Make version 4.2.1 fails to remove the trailing "$"
character as follows. I cannot attest to version 4.1 or 4.2 of Make, since I
don't have either of those versions installed.

--- BEGIN incorrect output ---
Makefile:2: CVS_BASE_TAG_NAME = v1.1.1beta.1 $
CVS_BASE_TAG_NAME = v1.1.1beta.1 $
----
make --version
