Thomas Petazzoni da76f0f155 package: enhance infrastructure to support source dir override 
When a variable <pkg>_OVERRIDE_SRCDIR is defined, then Buildroot will
no longer try to download, extract and patch the package. It will
simply use the value of this variable as the source directory for the
package. The contents of the package sources will be rsynced to the
package build directory in $(O)/build/pkg-version/.

This can be used to tell Buildroot that the sources for a given
package are inside some directory that you control, and which can be
versioned in Git/SVN, or handled in whichever way you want.

Those <pkg>_OVERRIDE_SRCDIR variables will be defined by a local
makefile included by Buildroot, which will be handled in a later
commit.

# Generic package infrastructure
#
# This file implements an infrastructure that eases development of
# package .mk files. It should be used for all non-autotools based
# packages. Autotools-based packages should use the specialized
# autotools infrastructure in package/Makefile.autotools.in.
#
# 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 informations about the package: name, version,
# download URL, etc.
#
# 2. Description of the commands to be executed to configure, build
# and install the package
#
# The autotools infrastructure specializes this generic infrastructure
# by already implementing the configure, build and install steps.

# UPPERCASE Macro -- transform its argument to uppercase and replace dots and
# hyphens to underscores
# Heavily inspired by the up macro from gmsl (http://gmsl.sf.net)
# This is approx 5 times faster than forking a shell and tr, and
# as this macro is used a lot it matters
# This works by creating translation character pairs (E.G. a:A b:B)
# and then looping though all of them running $(subst from,to,text)
