Function to display variable values

[Michael Morrell]

Is it possible to write a function that can display the value of an
arbitrary variable?  For example, I want a function "echo_var" that I can
use as:

FOO = hello
BAR = goodbye

$(call echo_var, FOO)
$(call echo_var, BAR)

that will print:

FOO = hello
BAR = goodbye

I tried:

define echo_var
echo $(1) = $($(1))
endef

but that didn't work.
