Previously we have hid almost all error messages from called tools like pkg-config or the compiler in the "configure" step. Only exceptions were the library checks because Carl-Daniel felt it improved usability in case of missing headers etc.
However, this makes the output of the makefile less readable and in the case of pkg-config fallbacks the error messages are actually expected. Instead of throwing a part of the detailed stderr outputs of the tools into the face of the users and completely hiding others, write all of them into a separate log file instead.
Also, disable implicit rules because we don't need them and they just make the build slower.
