Colin Cross f8dc89b49a Use split-long-arguments to touch pdk platform.zip files
touch $(_pdk_fusion_files) is too long for some systems, use
split-long-arguments to execute touch multiple times with a
subset of the list of files.

# pdk fusion if:
# 1) the platform.zip exists in the default location
# or
# 2) PDK_FUSION_PLATFORM_ZIP is passed in from the environment
# or
# 3) fusion is a command line build goal,
# PDK_FUSION_PLATFORM_ZIP is needed anyway, then do we need the 'fusion' goal?
# otherwise pdk only if:
# 1) pdk is a command line build goal
# or
# 2) TARGET_BUILD_PDK is passed in from the environment
# TODO: what's the best default location?
