Hi,
All versions of bash grok
for f in $VAR; do ...; done
where VAR is an empty shell variable. But
for f in $(VAR); do ...; done
where $(VAR) is an empty Makefile variable, leads to a syntax error with
bash 2.00..2.05. The solution is ugly...

* gnulib-tool (func_emit_lib_Makefile_am, func_emit_tests_Makefile_am):
Change mostlyclean-local rule to avoid sh syntax error from bash
versions 2.00..2.05 when $(MOSTLYCLEANDIRS) is empty.
