Submit #2955: Possibility to remove pthread_cancel symbol from libc

----------------------------------------
Stub pthread_cancel symbol in libc causes certain issues with gcc, specially with libgcc.so and libgfortran.so in gcc7 (likely other libs or utilities too, that define dummy weak pthread_cancel symbol to check if it gets claimed by anything).

So far in installed world with attached patch I didn't noticed any breakage in dports or base. gcc50 still has:
[rw at _ zsrc]$ readelf -s /usr/libexec/gcc50/gcc |grep pthread
     4: 0000000000000000     0 FUNC    WEAK   DEFAULT  UND pthread_mutex_unlock at DF404.0 (2)
     6: 0000000000000000     0 FUNC    WEAK   DEFAULT  UND pthread_once at DF404.0 (2)
    30: 0000000000000000     0 FUNC    WEAK   DEFAULT  UND pthread_mutex_lock at DF404.0 (2)
   120: 0000000000000000     0 NOTYPE  WEAK   DEFAULT  UND pthread_cancel
