m68k: Remove inline strcpy() and strcat() implementations
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) See also commit e00c73ee05dc38ecaccced55d4f5fc58b0b769f7 ("m68k: Remove inline strlen() implementation").
