Not sure if I should keep the patches as it seems that lfs no longer uses ` kbd-2.0.2-backspace-1.patch` , but it applies fine so  I kept it. 

Shouldn't we try to get `fix-euro-symbol-es-keymap.patch` upstream ? I don't use a spanish keyboard so I am not sure if it is correct the keyboard that way or if it was a personal preference of whoever added the patch
