[Buildroot] [PATCH] package/espeak: fix build issue with gcc6

[Romain Naour <romain.naour@gmail.com>]

On some architecture, "char" is signed (x86_64, nios2...) so the
compiler try to convert int 0xc2 and 0xba to a signed char.
This is an error since gcc6 (Wnarrowing).

cast string_ordinal init values.

Fixes:
