Pass "--as-needed" flag the linker through default system-wide LDFLAGS.
== Detailed description ==
The flag ("--as-needed") tells the linker to link in the produced
binary only the libraries containing symbols actually used by the
binary itself. This binary can be either a final executale or another
The use of the "--as-needed" flag allows the linker to avoid linking
extra libraries in a binary. This not only improves startup times (as
the loader does not have to load all the libraries for every step) but
might avoid the full initialization of big frameworks.
Well, --as-needed is workaround and nothing else. The real problem is
mess in makefiles and .pc (pkg-config) files.
It would be better to use --as-needed for testing purpose only, and
ask maintainers why the result with --as-needed is different.
