clang-8: error: unknown argument: '-flto-partition=none' when building lxml

[Luke Benes]

When I build with clang/linux I'm now seeing the following error:

Building lxml version 4.1.1.

I could be wrong, but I believe this error showed up when I updated my core OS. (Arch) I tried and older version of clang and an older version of the LibreOffice that used to compile and I'm now seeing this error there too.
