* libc/stdlib/ldtoa.c: Removed include of alloca.h.
        Also removed \r's.
        (asctoeg): Replaced alloca call with stack array and malloc
        when storage exceeds reasonable limit.
        (e53toe): Fixed einfin calls missing ldp parameter.
        (eiisinf): Hide behind check for LDBL_MANT_DIG == 64.
