Previously export_dynamic was set in src/makefiles/Makefile.$port. For solaris this required exporting with_gnu_ld. The determination of with_gnu_ld would be nontrivial to copy for meson PGXS compatibility. It's also nice to delete libtool.m4. This uses -Wl,--export-dynamic on all platforms, previously all platforms but FreeBSD used -Wl,-E. The likelihood of a name conflict seems lower with the longer spelling.
