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.
