[svn-r26633] Add -D_DEFAULT_SOURCE to CPPFLAGS on Linux systems. -D_BSD_SOURCE is deprecated

Browse Source 
in recent versions of glibc, and -D_DEFAULT_SOURCE is the replacement.  Keep
-D_BSD_SOURCE for now to support older systems.  gcc will not issue a warning
about -D_BSD_SOURCE being deprecated when -D_DEFAULT_SOURCE is supplied as well.

Tested: jam, koala, ostrich (h5committest)
