Prevent GNU use from expanding dollar signs in environment variables
Is there a way for GNU to make the interpretation of dollar signs literally in environment variables?
Take this makefile:
echoFOO:
echo '$(FOO)'
Run it like this:
$ FOO='a$bc' make
echo 'ac'
ac
I wish this would literally pronounce the letter $ bc, but I can't seem to find a way to get GNU Make to save its damn hands from environment variables.

Two ways to get the result you want to see. Compromises with both.
$ cat Makefile
all: echoFOO echovFOO
echoFOO:
echo '$(FOO)'
echovFOO:
echo '$(value vFOO)'
$ FOO='a$$bc' vFOO='a$bc' make
echo 'a$bc'
a$bc
echo 'a$bc'
a$bc
