Usage of Balloc in Newlib

[Sebastian Huber]

Hello,

the Balloc() function can return NULL in case _calloc_r() returns NULL.  All 
users of Balloc() in Newlib don't check for a NULL pointer.  Is this Balloc() 
supposed to never fail?

./libc/stdlib/strtod.c:         bd = Balloc(ptr,bd0->_k);
./libc/stdlib/strtod.c-         Bcopy(bd, bd0);
