Qmake attempts to invoke the linker with the default `g++` binary even when we changed the binary. This will compile error when using LTO. For clang: ``` /usr/bin/ld.gold: error: /usr/lib/llvm-3.8/bin/../lib/LLVMgold.so: could not load plugin library: /usr/lib/llvm-3.8/bin/../lib/LLVMgold.so: cannot open shared object file: No such file or directory ``` For GCC: ``` lto1: fatal error: bytecode stream generated with LTO version 6.0 instead of the expected 4.1 ```
