Nikita Popov 1115746e65 Make lto handling similar to current rawhide
Have a --with lto_build option, where LTO is enabled by default
for everything except i686 and riscv. Use that flag to condition
whether `-DLLVM_UNITTEST_LINK_FLAGS` is passed.

Additionally, make use of the new Fat LTO functionality in rawhide
to use `-fno-lto` instead of `-Wl,-plugin-opt=O0` to save more
time linking unit tests.
