The RedHat bug suggests 'static const' as the appropriate replacement.

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=114610#c4

Unfortunately that probably means an extra 64 bytes of text, rather than
the 10 or so bytes of instructions to do the memset and store. Ideally
padding[] would be allocated in BSS rather than text or the stack (and
initialized with { 0x80, } at runtime), but I guess you can't have
everything.
