autoconf: Move export_dynamic determination to configure
Previously export_dynamic was set in src/makefiles/Makefile.$port. For solaristhis required exporting with_gnu_ld. The determination of with_gnu_ld would benontrivial to copy for meson PGXS compatibility. It's also nice to deletelibtool.m4.This uses -Wl,--export-dynamic on all platforms, previously all platforms butFreeBSD used -Wl,-E. The likelihood of a name conflict seems lower with thelonger spelling.Discussion:https://postgr.es/m/20221005200710.luvw5evhwf6clig6@awork3.anarazel.de
