Yann E. MORIN 1f6b283dd9 package/pkg-*.mk: do not conditionally set empty variables
Setting an unset variable to an empty value is useless in make; an unset
variable just expands to an empty string anyway. So what we do currently
has no side effect:

    variable set and not empty   -> variable not modified
    variable set and empty       -> variable not modified
    variable unset               -> set to an empty string

However, additional variables do have an impact on the parsing time of
the Makefiles, and the more variables, the more collisions in the hash
table used internally by make, which slows down the parsing.

By dropping those conditionally-set-empty variables, we gain about 3%:

    Run     Before  After
    1       5.572   5.325
    2       5.434   5.354
    3       5.490   5.320
    4       5.525   5.330
    5       5.476   5.330
    6       5.511   5.434
    7       5.498   5.388
    8       5.524   5.371
    9       5.479   5.346
    10      5.637   5.324
    Mean:   5.515   5.352

Yeah, 0.163s does not look like much, and this does not make
autocompletion any more usable. Still, that 3% gain is not to be
ashamed of either.

Note that there are 3 others case where we do set empty variables, but
those are unconditional and serve other purposes:

  - pkg-virtual: this is done on purpose to avoid a bug when the
    environment may have TOOLCHAIN_VERSION or _SOURCE set, and we really
    want those to be empty, so the assignment is not conditional;

  - pkg-python: the reason for setting those to empty is dubious at
    best; it's been there since the inception of the python infra, back
    in 2013; still, the case is different than this patch addresses;

  - pkg-toolchain-external: this is the case for a toolchain already
    installed, so indeed we want to set _SOURCE and _VERSION to empty.

# Generic package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files. It should be used for packages that do not rely
# on a well-known build system for which Buildroot has a dedicated
# infrastructure (so far, Buildroot has special support for
# autotools-based and CMake-based packages).
#
# See the Buildroot documentation for details on the usage of this
# infrastructure
#
# In terms of implementation, this generic infrastructure requires the
# .mk file to specify:
#
# 1. Metadata information about the package: name, version,
# download URL, etc.
#
# 2. Description of the commands to be executed to configure, build
# and install the package

#
# To protect against the case that the output or staging directories or

# Note that STAGING_DIR can be outside BASE_DIR when the user sets

# - pkgdir and pkgname should be referenced with a single dollar sign too. These
# functions rely on 'the most recently parsed makefile' which is supposed to
# be the package .mk file. If we defer the evaluation of these functions using
# double dollar signs, then they may be evaluated too late, when other
# makefiles have already been parsed. One specific case is when $$(pkgdir) is
# assigned to a variable using deferred evaluation with '=' and this variable
# is used in a target rule outside the eval'ed inner block. In this case, the
# pkgdir will be that of the last makefile parsed by buildroot, which is not
# the expected value. This mechanism is for example used for the TARGET_PATCH
# rule.
# - All other variables should be referenced with a double dollar sign:
# $$(TARGET_DIR), $$($(2)_VERSION), etc. Also all make functions should be
# referenced with a double dollar sign: $$(subst), $$(call), $$(filter-out),
# etc. This rule ensures that these variables and functions are only expanded
# during the $(eval) step, and not earlier. Otherwise, unintuitive and
# undesired behavior occurs with respect to these variables and functions.
