    bfd: Define ___lc_codepage_func prototype for older MinGW-w64
    
    In commit 68e80d96a84282d547f3b3c1234c99009521630c, the usage of
    ___lc_codepage_func was introduced to determine the current encoding.
    
    Prior to version 9.0 of MinGW-w64, the function prototype for
    ___lc_codepage_func was missing and trying to build BFD caused the
    following error:
    
    error: implicit declaration of function ‘___lc_codepage_func’
    
    This changeset adds a conditonal definition of
    ___lc_codepage_func to allow a sucessful build with MinGW-w64.
