They should never be overridden in a single object 308# files. 309# - TARGETTYPE is the type of linktarget as some platforms need very different 310# command to link different targettypes. 311# - VERSIONMAP is the linker script, usually used to version a dynamic 312# library's symbols (on *nix/Mac). 313# 314# Since most variables are set on the linktarget and not on the object, the 315# object learns about these setting via GNU makes scoping of target variables. 316# Therefore it is important that objects are only directly depended on by the 317# linktarget. This for example means that you cannot build a single object 318# alone, because then you would directly depend on the object. 319# 320# A note about flags: because the overriding the global variables with a target 321# local variable of the same name is considered obscure, the target local 322# variables have a T_ prefix. 323define gb_LinkTarget_LinkTarget 324$(call
