A slightly more involved test

[ron minnich]

rminnich-macbookair:tmp rminnich$ cat mkfile
</$objtype/mkfile
all:
echo $objtype
echo $MKSHELL
rminnich-macbookair:tmp rminnich$ mk
echo $objtype
echo $MKSHELL
amd64
sh
rminnich-macbookair:tmp rminnich$ echo $MKSHELL $objtype
/bin/rc amd64
rminnich-macbookair:tmp rminnich$

and it's not picking up the variable for objtype:
65901/0x31695: read(0x3, "</$objtype/mkfile\nall:\n\techo
$objtype\n\techo $MKSHELL\n\0", 0x2000) = 53 0
65901/0x31695: open("//mkfile\0", 0x0, 0x0) = -1 Err#2

thanks
