[PATCH] D27739: Disable libLTO tests when libLTO is not built

[Mehdi AMINI via Phabricator via llvm-commits]

mehdi_amini added a comment.

An alternative to checking for the existence of the file is to change `llvm/test/lit.site.cfg.in` to add to the config the value of `LLVM_TOOL_LTO_BUILD`, and it would be available directly here.
