Remove harmful rpath in LDFLAGS and fix logic for cargo.

[xambroz]

This patch is from Debian libemu package - libemu-03_remove_rpath_and_fix_ldflags.patch https://packages.debian.org/search?searchon=sourcenames&keywords=libemu

Description: Remove harmful rpath in LDFLAGS and fix logic for cargo. Before this patch, libemu was searching for includes and also had an rpath for libraries in /usr/local/lib. Also the logic for libcargo is wrong, as makes the content of LDFLAGS empty if cargo is enabled but there are no headers in the system. This was preventing proper hardening to be activated in Debian.
