    Fix gcc gperf prototypes to avoid redeclaration errors
    
    Otherwise, building stable/12's gcc on recent -CURRENT will result in
    redeclaration errors:
    
    In file included from /usr/src/contrib/gcc/cp/except.c:892:
    /usr/src/contrib/gcc/cp/cfns.gperf:20:1: error: conflicting types for 'hash'
    hash (register const char *str, register size_t len)
    ^
    /usr/src/contrib/gcc/cp/cfns.gperf:5:21: note: previous declaration is here
    static unsigned int hash (const char *, unsigned int);
                        ^
    /usr/src/contrib/gcc/cp/cfns.gperf:78:1: error: conflicting types for 'libc_name_p'
    libc_name_p (register const char *str, register size_t len)
    ^
    /usr/src/contrib/gcc/cp/cfns.gperf:9:14: note: previous declaration is here
    const char * libc_name_p (const char *, unsigned int);
                 ^
    
    Direct commit to stable/12, since gcc is gone in stable/13 and later.
