Build fails on a clang/lld based system: ld.lld: error: undefined symbol: gtk_sensorstacho_new(GtkOrientation, unsigned int, SensorsTachoStyle)
In Gentoo Linux it's possible to use the clang/lld as system compiler instead of gcc/binutils.
Current stable 1.4.4 builds fine in Gentoo as long as gcc/binutils is used but fails to build with clang/lld:
