pennae 2799fe4cdb enable LTO in optimized builds
gives 2-5% performance improvement across a board of tests.
LTO is broken when using clang; some libs link fine while others crash
the linker with a segfault in the llvm linker plugin. 🙁

Sergei Trofimovich 579dcbabd5 mk: prefert inplace library paths to system ones (take 2)
It's a second attempt to merge the change. Previous attempt
was reverted in b976b34a5b.
Since then underlying failure exposed by original change was
fixed by https://github.com/NixOS/nix/pull/5354.

Below goes description of original change:

The link failure happens on a system with stable nix-2.3.15
installed in /usr/lib64 (it's libutil.so API differs from master):

```
LANG=C make V=1
g++ -o /home/slyfox/dev/git/nix/src/libstore/libnixstore.so \
    -shared -L/usr/lib64 -Wl,--no-copy-dt-needed-entries \
    src/libstore/binary-cache-store.o ... src/libstore/uds-remote-store.o \
    -lsqlite3 -lcurl -lsodium -pthread -ldl -lseccomp -Wl,-z,defs -Wl,-soname=libnixstore.so
      -Wl,-rpath,/home/slyfox/dev/git/nix/src/libutil -Lsrc/libutil -lnixutil
ld: src/libstore/binary-cache-store.o: in function `nix::BinaryCacheStore::BinaryCacheStore(
    std::map<std::__cxx11::basic_string<char, std::char_traits<char>, ...
nix/src/libstore/binary-cache-store.cc:30: undefined reference to `nix::readFile(
    std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' ...
...
```

This happens due to `-L/usr/lib64 -Lsrc/libutil` search path ordering.
The change turns it into `-Lsrc/libutil -L/usr/lib64`.

Closes: https://github.com/NixOS/nix/issues/3087

Sergei Trofimovich fe068eca00 mk: add support for passing LDFLAGS to libs and bins
autotools-based systems usually allow user to
append own LDFLAGS like
    LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu"
at ./configure stage

This change plumbs LDFLAGS through similar to existing CXXFLAGS variable.

Eelco Dolstra 4ee6001f95 GNU Make 3.81 compatibility
3.81 doesn't understand the ‘define foo =’ syntax, which was added in
3.82.  So use ‘define foo’ instead.
