ccache: update to 4.1

2020-12-31T09:03:21Z

Upstream switched to building with CMake. Adjust accordingly. Reapplied patch as upstream changed the file format. Added HOST_BUILD_PARALLEL for faster compilation. Added cmake tool dependency and removed circular dependencies as a result. Adjusted dependent tools to use NOCACHE as they are needed to build ccache. Signed-off-by: Rosen Penev

pkgconf: always retain -I and -L flags

2020-03-15T19:32:10Z

The pkgconf fork filters -I and -L flag values from .pc files which match pkgconf's builtin system directory value. During configure, pkgconf derives the default system include and library search path values from exec_prefix, which is set to staging_dir/host in the host tool build phase. Due to that, pkgconf will drop all -I and -L flags pointing to staging_dir/host/include or staging_dir/host/lib, unless invoked with --keep-system-cflags and --keep-system-libs respectively, breaking our kernel libelf discovery / stack validation workarounds. In order to inhibit the filtering, add --keep-system-cflags and --keep-system-libs to our pkg-config shell wrapper.

tools/pkg-config: Replace with pkgconf

2020-03-01T20:36:00Z

pkgconf is a newer, actively maintained implementation of pkg-config that supports more aspects of the pkg-config file specification and provides a library interface that applications can use to incorporate intelligent handling of pkg-config files into themselves (such as build file generators, IDEs, and compilers). Through its pkg-config compatibility interface (activated when it is run as "pkg-config"), it also can completely replace the original implementation. It is also lighterweight and does not require glib2, as pkg-config does. On other distros, pkgconf is symlinked to pkg-config. For simplicity here, it is renamed to pkg-config.real, as in the original package. Initial results have been positive. As before, pkgconf works as long as the pkg-config files point to the proper paths. Signed-off-by: Rosen Penev [backported upstream fix for Meson] Signed-off-by: Petr Štetiar
