This for example means that you cannot build a single object 316# alone, because then you would directly depend on the object. 317# 318# A note about flags: because the overriding the global variables with a target 319# local variable of the same name is considered obscure, the target local 320# variables have a T_ prefix. 321define gb_LinkTarget_LinkTarget 322$(call
