The attached patch fixes the expected class file name for source files
with hyphenated names by mangling "-" to "$Mn".

Previously, the simple glob mapped *.scm to *.class, which meant that
for string-cursors.scm it was looking for "string-cursors.class", not
finding it, and always concluding that it was out-of-date.  (Likewise
for case-lambda.scm and process-context.scm.)
