Subject: [PATCH] ocaml: Link the C bindings with LDFLAGS (RHBZ#1548536).
Use the ocamlmklib -ldopt flag to pass the general $(LDFLAGS) when
calling gcc to link dllmlhivex.so. We were already passing $(CFLAGS)
when building the object file.
When building using Fedora's standard hardening flags this gives:
ocamlmklib -o mlhivex hivex_c.o hivex.cmo \
-verbose -ldopt '-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld' \
-L../lib/.libs -lhivex
+ gcc -shared -o ./dllmlhivex.so hivex_c.o -Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -L../lib/.libs -lhivex
+ ar rc ./libmlhivex.a hivex_c.o; ranlib ./libmlhivex.a
+ /usr/bin/ocamlc -a -o mlhivex.cma hivex.cmo -dllib -lmlhivex -cclib -lmlhivex -cclib -L../lib/.libs -cclib -lhivex
This also works if $(LDFLAGS) is empty, because ocamlmklib ignores
-ldopt ''.
