Like it used to behave before this bump, a few paths (libdir, includedir, etc.) are prefixed by the sysroot, and other paths are not. However, the behavior changes when a path, such as dridriverdir, is defined in terms of ${libdir}. With the older pkg-config, dridriverdir was not sysroot-prefixed. With the new pkg-config, it will be sysroot-prefixed, because pkg-config really resolved the value of libdir, which is sysroot-prefixed. dridriverdir is used on the target and not at build time, so we don't want it to be sysroot-prefixed. As reported by #11591, the xerver fail to load dri modules (r600_dri.so): >From Xorg.0.log: (EE) AIGLX error: dlopen of /full/path/to/sysroot/usr/lib/dri/r600_dri.so failed (/full/path/to/sysroot/usr/lib/dri/r600_dri.so: cannot open shared object file: No such file or directory) (II) GLX: no usable GL providers found for screen 0 That's because the xserver hardcode the dri divers directory path in DRI_DRIVER_PATH which come from dridriverdir=`$PKG_CONFIG --variable=dridriverdir dri` We can see in dri.pc that dridriverdir use libdir which is now prefixed by the sysroot by pkgconf 1.5.3: prefix=/usr exec_prefix=/usr libdir=${exec_prefix}/lib includedir=${prefix}/include dridriverdir=${libdir}/dri Since we can't rely on pkgconf anymore, use --with-dri-driverdir="/usr/lib/dri" to use explicitly "/usr/lib/dri" instead of relying on dri.pc.
