Jo-Philipp Wich 6de7406d54 pkgconf: always retain -I and -L flags ... 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.
