[svn-r11185] Purpose:
Makefile feature

Description:
'make check-clean' now cleans *.h5 files created by tests as well as
.log and .chkexe files.

Solution:
check-clean is now a separate target in its own right, which cleans less
than mostlyclean (check-clean < mostlyclean < clean < distclean).

Platforms tested:
mir, heping, modi4 (serial and parallel)
