Thanks! Included.

In short, it's because TMP_DIR is a template and not a
constant.

------------------------------------------------------------------

$(TMP_DIR) needs to be evaluated on each occurence ("TMP_DIR = ..."),
rather than once and for all ("TMP_DIR := ...").

$(TMP_DIR) references "$(1)":

    TMP_DIR = $(PWD)/tmp-$(1)

which is set to a different value on each evaluation via $(call ...):

    $(call TMP_DIR,$(PKG))

where $(PKG) is iterated over the list of packages via the $(foreach ...)
macro:

    $(foreach PKG, ..., ... $(call TMP_DIR,$(PKG)) ...)

------------------------------------------------------------------

Of course, I could have used a prefix and a suffix variable instead,
such as:

    TMP_DIR_PREFIX := $(PWD)/tmp-
    TMP_DIR_SUFFIX :=

But I thought a template was more clear:

    TMP_DIR = $(PWD)/tmp-$(1)
