The configuration cache shared between packages, while being in principle a nice idea to speed-up the configuration of packages by avoiding repetitive identical checks, turned out to be unreliable due to the subtle differences between similar but not identical checks in different packages. After spending some time trying to fix those, we concluded that supporting the shared configuration cache is definitely too hard and too unreliable, and that we'd better get rid of it altogether. This patch therefore removes the shared configuration cache infrastructure and usage.

# Autotools package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for autotools packages. It should be used for all
|
|
# packages that use the autotools as their build system. Non-autotools
|
|
# packages should use the generic infrastructure in
|
|
# package/Makefile.package.in.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this autotools infrastructure requires
|
|
# the .mk file to only specify metadata informations about the
|
|
# package: name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default autotools behaviour. The
|
|
# package can also define some post operation hooks.
|
|
