  Maybe we should generalize this, and export the elements of 
TARGET_MAKE_ENV for all target goals:

ifeq ($(5),target)
$$($(2)_TARGET_INSTALL_TARGET):         export PATH=$(TARGET_PATH)
$$($(2)_TARGET_INSTALL_STAGING):        export PATH=$(TARGET_PATH)
$$($(2)_TARGET_INSTALL_IMAGES):         export PATH=$(TARGET_PATH)
$$($(2)_TARGET_INSTALL_HOST):           export PATH=$(TARGET_PATH)
$$($(2)_TARGET_BUILD):                  export PATH=$(TARGET_PATH)
$$($(2)_TARGET_CONFIGURE):              export PATH=$(TARGET_PATH)
$$($(2)_TARGET_RSYNC):                  export PATH=$(TARGET_PATH)
$$($(2)_TARGET_RSYNC_SOURCE):           export PATH=$(TARGET_PATH)
$$($(2)_TARGET_PATCH):                  export PATH=$(TARGET_PATH)
$$($(2)_TARGET_EXTRACT):                export PATH=$(TARGET_PATH)
$$($(2)_TARGET_SOURCE):                 export PATH=$(TARGET_PATH)
$$($(2)_TARGET_UNINSTALL):              export PATH=$(TARGET_PATH)
$$($(2)_TARGET_CLEAN):                  export PATH=$(TARGET_PATH)
$$($(2)_TARGET_DIRCLEAN):               export PATH=$(TARGET_PATH)
endif

  And so on for all the other variables. Unfortunately you need a 
separate line for each variable, you can't do something like 'export 
$(TARGET_MAKE_ENV)' on the right-hand side.

  Anyway, it's just an idea, cause it's quite a big change that will 
probably break some things.

  Arnout
