Or we could copy the bytecode (when it’s foreign) instead of mmapping
it, and translate instructions that are endianness-sensitive.

Now, I agree it’s a big task, and one I’d rather avoid 2 months before

Out of curiosity, are .pyc endianness- and word-size-sensitive?

What about .elc?

Guile itself currently installs ‘.go’ under $pkgdatadir.  That would
need to be changed to $pkglibdir/1.9, right?

Also we now have $GUILE_LOAD_PATH and $GUILE_LOAD_COMPILED_PATH.  Should
we also have an equivalent to ‘-L’?
