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.
