    m68k: Remove inline strcpy() and strcat() implementations · d346a5db
    Geert Uytterhoeven authored
    Gcc may replace calls to standard string functions by open code and/or
    calls to other standard string functions. If the replacement function is
    not available out-of-line, link errors will happen.
    
    To avoid this, the out-of-line versions were provided by
    arch/m68k/lib/string.c, but they were usually not linked in anymore as
    typically none of its symbols are referenced by built-in code.
    However, if any module would need them, they would not be available.
    
    Hence remove the inline strcpy() and strcat() implementations, remove
    arch/m68k/lib/string.c, and let the generic string library code handle it.
    
    Impact on a typical kernel build seems minimal or nonexistent:
    
    -      .text : 0x00001000 - 0x002aac74   (2728 KiB)
    -      .data : 0x002ada48 - 0x00392148   ( 914 KiB)
    +      .text : 0x00001000 - 0x002aacf4   (2728 KiB)
    +      .data : 0x002adac8 - 0x00392148   ( 914 KiB)
