Switching to this way of doing crypt() adds 132 bytes of overhead total.
I do not personally think 132 bytes is enough to be concerned about.

petrie:~/uClibc$ ~/dev-src/linux/scripts/bloat-o-meter ./lib-origin-master/libcrypt-0.9.33-git.so ./lib/libcrypt-0.9.33-git.so
add/remove: 1/0 grow/shrink: 1/0 up/down: 132/0 (132)
function                                     old     new   delta
crypt                                         92     192    +100
crypt_impl_tab                                 -      32     +32
