An odd build question...

On an x86_64 Linux system we observe a configure line like the following

CC=mpicc FC=mpif90 CFLAGS="-g -O3 -fPIC" FFLAGS="-g -O3 -fPIC" \
        ./configure --disable-dependency-tracking \
        --enable-parallel --enable-fortran --enable-shared

used with the Intel 11.1 compilers causing the installed
libhdf5.so.6.0.4 (from release 1.8.5-patch1) to contain no symbols
(according to objdump -t).  The same configure line shows
libhdf5.7.0.1 (from release 1.8.7) as containing symbols.  I see the
libtool-build shared libraries in src/.libs matching the installed .so
files.

Has there been some known change between 1.8.5-p1 and 1.8.7 that would
cause this difference?  FWIW I also see if for serial builds.  I've
not been able to dig an origin out of the release announcements.

Thanks,
Rhys
