Make bug related to backquotes

[Pierre B]

The problem is with the backquote AND/OR addprefix.
The following makefile illustrates the bug.

Notice the doubled ././ in the test output.
Version information is in the output.

#
# Make file illustrates a problem with back quote
# by juxtaposing results with back quote and shell

nice_string:=$(shell ls *.tst)#

buggy_string:=`ls *.tst`#

cat_buggy:=foo ${buggy_string}#

cat_nice:=foo ${nice_string}#

test:
        -rm *.tst
        @ echo
        echo test1 >test1.tst
