[svn-r25067] Fix for HDFFV-8276, the --disable-sharedlib-rpath configure optino doesn't remove rpaths from the library files, was checked into trunk in September 2013, but not into the 1.8 branch.  part of the code was merged to v1.8 in the interim for fortran, but not for hl or c++.  The rest is merged in this revision.
The --disable-sharedlib-rpath option seems to have no effect on non-Linux platforms.

Tested with h5committest on jam, koala, ostrich and platypus.
Tested with --disble-sharedlib-rpath option on jam, platypus, emu and quail.
Absence of rpaths verified on jam and platypus.
