[svn-r27189] Merge change from hdf5_1_8_15 to hdf5_1_8.

Chane addressed HDFFV-9010:  configure issue with gcc 4.9.2; libtool produced "-l " with no lib name.
Also Scot noted that the -i option for sed does not work on Solaris or Mac, so the sed output is written to a temp file and then moved to the libtool file

Tested h5committest.
