GCC automatically detects when it is linking LTO objects, but clang does
not. Add -flto to LDFLAGS to make this work for clang too.

(cherry picked from commit 26ee6ff6ad)
Add the 'lto' option to enable building with link time optimization
by adding '-flto' to both CFLAGS and CXXFLAGS. The 'lto' option can
be specificed both in the PKGBUILD or by setting the default in
makepkg.conf.

buildenv is set once for build() and a second time for package(). When
using both distcc and ccache, this lead to CCACHE_PREFIX="distcc distcc"
in package(), which breaks PKGBUILDs that execute the compiler in
package() because distcc complains:
distcc[383041] (main) CRITICAL! distcc seems to have invoked itself
recursively!
Avoid causing this error by only adding "distcc" to CCACHE_PREFIX if
it's not yet there.

The rust language supports $RUSTFLAGS to be used automatically in all
rustc invocations. Allow setting this in makepkg.conf (e.g. for
optimization or debuginfo support), and teach debug+strip to pass the
rustc command line argument necessary to rewrite source file paths in
the debugging symbols.

This opens the door for third parties to provide libmakepkg
extentions for the purpose of altering the build environment.
