No, the correct use of pkg-config is to pass the PKG_CONFIG_SYSROOT_DIR
environment variable.

if the staging variable contains the directory which was used as DESTDIR
when installing xenomai, you should run pkg-config with the following
environment variables set:

PKG_CONFIG_LIBDIR=${staging}/usr/lib/pkgconfig:${staging}/usr/share/pkgconfig

PKG_CONFIG_SYSROOT_DIR=${staging}
