Nice one.

The make within a make (even though the sub-make is in a shell script)
prints out 'make entering directory /tmp...', which becomes part of
that shell scripts $t, which is why sed doesn't understand the command
'm' (the first letter of 'make entering...').

You can see (after wading through the output) exactly how it happens
by running

  make -r -d -f maketest test

(-r tells it not to try any built-in rules, lessening the output,
the -d, tells it to run in 'debug' mode letting us see what it does
step by step).

The fix (one fix, anyway) is to tell that inside make to be "silent"
(-s) like this:
 
t=`make -s -f - <<EOF
all:
        @echo $weird
EOF`
