Add O3 flag to linker call for GCC

Add O3 to gcc linker
...
It is unknown if gcc uses the O3 optimization levels passed to the
compilation of individual cpp files, or if it needs O3 passed to the
linker as well.
The hash of the final binaries are different, thus O3 is passed to the
linker.

Disable LTO on Travis CI and change clang binary to clang++
...
Travis clang does not have the LLVMgold plugin installed.
Disabling LTO is easier than installing the plugin since the CI doesn't
create any artifacts anyway.

Update Linux compiler selection with linker
...
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
```

Add link time optimization to clang/gcc builds
...
Using `-flto` on clang without using the gold linker produces the error:
```main.o: file not recognized: File format not recognized```
https://github.com/android/ndk/issues/242
`gold` seems to be faster than `ld`, and decently tested even in 2010:
https://stackoverflow.com/questions/3476093/replacing-ld-with-gold-any-experience
Qmake will still append `-Wl,-O1` even though higher optimization levels
are used. Removing this in order to keep the compile command as short as
possible, and to reduce weird issues down the line. Ref topic:

CircleCI Xenial does not come with an up to date version of Clang. It is
therefore required to get the newest version (8). The .pri file has
