    build: Remove -fno-stack-protector-all from EMBEDDED_EXTRA_CFLAGS
    
    This seems to have been introduced in commit f8beb54e2455 ("Disable PIE/SSP
    features when building Xen, if GCC supports them.") in 2004.
    
    However, neither GCC nor Clang appear to have ever supported taking the
    negated form of -fstack-protector-all, meaning this been useless since its
    introduction.
