Similarly to what was done for bug #175125, we should use the value of the “Cflags” field from “epoxy.pc”. In most cases it will be empty, but the correct thing is respecting it. Example: changes like https://github.com/anholt/libepoxy/pull/113 may result in the “Cflags” field being populated, and it's better to make WebKit pick its value that being bitten by build failures in the future and/or in less desktop-y platforms.
