[svn-r11646] Purpose:

Bug fix/feature

Description:
Added support for -shlib in h5fc and h5c++.
Made check-install use -shlib when only shared libraries have been installed.

Solution:
h5fc and h5c++ didn't recognize -shlib.  Stole code from h5cc to link against
shared libraries.
When static libraries are disabled, the examples Makefiles will automatically
use the -shlib option to link against shared libraries.  Thus,
--disable-static and make check-install should work together.

Platforms tested:
heping(disable-static, enable-static, fortran, c++), modi4 (disable-static, fortran, c++, parallel, enable-static)
