    [UML] fix gcc ICEs and unresolved externs · 4f81c535
    Jeff Dike authored
    There are various constraints on the use of unit-at-a-time:
     - i386 uses no-unit-at-a-time for pre-4.0 (not 4.3)
     - x86_64 uses unit-at-a-time always
    
    Uli reported a crash on x86_64 with gcc 4.1.2 with unit-at-a-time,
    resulting in commit c0a18111
    
    Ingo reported a gcc internal error with gcc 4.3 with no-unit-at-a-timem,
    resulting in 22eecde2
    
    Benny Halevy is seeing extern inlines not resolved with gcc 4.3 with
    no-unit-at-a-time
    
    This patch reintroduces unit-at-a-time for gcc >= 4.0, bringing back the
    possibility of Uli's crash.  If that happens, we'll debug it.
    
    I started seeing both the internal compiler errors and unresolved
    inlines on Fedora 9.  This patch fixes both problems, without so far
    reintroducing the crash reported by Uli.
