Sorry, yes, you will need exactly that argument.

You ran these in the wrong directory.  What I suggested is:

   cd mit-scheme/src
   (cd microcode && ./configure)
   make -j4 cross-target
   env FAST=y make check

In the second line, `(cd microcode && ./configure)' (where you guessed
correctly that you need to add --enable-native-code=svm1-32le), I
meant the parentheses literally -- that runs the commands in a
subshell, so it doesn't change the directory you're in.

In other words, you need to:

1. run `./configure --enable-native-code=svm1-32le' in
   mit-scheme/src/microcode, and then

2. run `make -j4 cross-target' in mit-scheme/src (NOT in
   mit-scheme/src/microcode), and then

3. run `env FAST=y make check' in mit-scheme/src (NOT in
   mit-scheme/src/microcode).

Yes, make install has no chance of working if the build didn't finish.
