Fabio Porcedda 22b327fc74 pkg-luarocks: fix top-level parallel makefile support
In the *-install-target phase the manifest file is being updated, if multiply packages try to update it they fail.

To avoid multiple access to the manifest file use flock to sync
multiple luarocks packages.

e.g. installing three luarocks packages:
make lua-cjson-build lua-coat-build lua-coatpersistent-build
make lua-cjson lua-coat lua-coatpersistent -j

Fix error:
Updating manifest for /home/tetsuya/buildroot/br2/output/target/usr/lib/luarocks/rocks
No existing manifest. Attempting to rebuild...

Error: rock_manifest file not found for lua-coat 0.9.1-1 - not a LuaRocks 2 tree?

[Thomas: get rid of LUAROCKS_RUN, and use LUAROCKS_RUN_ENV +
LUAROCKS_RUN_CMD everywhere.]

# LuaRocks package infrastructure
# see http://luarocks.org/
#
# This file implements an infrastructure that eases development of
# package .mk files for LuaRocks packages.
# LuaRocks supports various build.type : builtin, make, cmake.
# This luarocks infrastructure supports only the builtin mode,
# the make & cmake modes could be directly handled by generic & cmake infrastructure.
#
# See the Buildroot documentation for details on the usage of this
# infrastructure
#
# In terms of implementation, this LuaRocks infrastructure requires
# the .mk file to only specify metadata information about the
# package: name, version, etc.

# inner-luarocks-package -- defines how the configuration, compilation and
# installation of a LuaRocks package should be done, implements a few hooks to
# tune the build process and calls the generic package infrastructure to
# generate the necessary make targets
#
# argument 1 is the lowercase package name
# argument 2 is the uppercase package name, including a HOST_ prefix
# for host packages
# argument 3 is the uppercase package name, without the HOST_ prefix
# for host packages
# argument 4 is the type (target or host)
