    purgatory: fix disabling debug info
    
    [ Upstream commit d83806c4c0cccc0d6d3c3581a11983a9c186a138 ]
    
    Since 32ef9e5054ec, -Wa,-gdwarf-2 is no longer used in KBUILD_AFLAGS.
    Instead, it includes -g, the appropriate -gdwarf-* flag, and also the
    -Wa versions of both of those if building with Clang and GNU as.  As a
    result, debug info was being generated for the purgatory objects, even
    though the intention was that it not be.
    
    Fixes: 32ef9e5054ec ("Makefile.debug: re-enable debug info for .S files")
