using makefile variables in shell script without running make

linux bash shell makefile

You could use (a modified version of) the print-% target from Makefile hacks: print the value of any variable in your makefile to let you query it for values.

print-%:        @echo '$(subst ','\'',$($*))'

linux bash shell makefile

TEST_ENV=$(make -qp | awk -F' = ' '$1=="TEST_ENV" {print $2}')

I'm sure there are edge cases this doesn't handle, but it's a decent start. Rudimentary testing shows this handles multi-line variables.
