Make sure the calling function strcspn() is inlined into also uses
alloca() (preferably with a variable argument, but I think GCC currently
doesn't optimize it even for a constant) so that %ebp is used for the
frame pointer and therefore unavailable.
Building strcspn() standalone certainly is going to work.
