Makefile: Honour LDFLAGS for binary targets

Browse Source 
We don't set any, but we should use them if they are passed in the
environment. On a Fedora Rawhide package build, annocheck
(https://sourceware.org/annobin/) reports:

  Hardened: /usr/bin/passt: FAIL: bind-now test because not linked with -Wl,-z,now

...despite the build system exporting -Wl,-z,now in LDFLAGS.
