hurd: Also make it possible to call strlen very earlyHEADmaster
strlen, which is another ifunc-selected function, is invoked during early static executable startup if the argv arrives from the exec server. Make it not crash. Checked on x86_64-gnu: statically linked executables launched after the exec server is up now start up successfully.
