crt: Fix builtin declaration mismatch warning with ssp functions

This fixes the following warnings with gcc
warning: mismatch in argument 2 type of built-in function '__memmove_chk'; expected 'const void *' [-Wbuiltin-declaration-mismatch]
warning: mismatch in argument 2 type of built-in function '__memcpy_chk'; expected 'const void *' [-Wbuiltin-declaration-mismatch]
warning: mismatch in argument 2 type of built-in function '__mempcpy_chk'; expected 'const void *' [-Wbuiltin-declaration-mismatch]
