This means options=('!buildflags') will disable the addition of CFLAG
etc for LTO and debug building.

(cherry picked from commit 42fe4864a0)
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.
