    sparc: Char arrays are 64-bit aligned on SPARC
    
    pr88077 fails on SPARC since char HeaderStr[1] in pr88077_1.c and
    long HeaderStr in pr88077_0.c differs in alignment.
    
    Warning printed by Binutils ld:
    warning: alignment 4 of normal symbol `HeaderStr' in c_lto_pr88077_0.o is
    smaller than 8 used by the common definition in c_lto_pr88077_1.o
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/lto/pr88077_0.c: Change type to match alignment for SPARC
