Use libtool -export-dynamic flag for portability 

The linker flag required for exporting symbols in executables varies
by platform.  libtool handles this with a single -export-dynamic
flag (not to be confused with the similarly-named ELF linker flag)
which tells it to use the correct platform-specific flag at link time.
