[PATCH v2 06/40] tests/tcg/minilib: Constify digits in print_num

[Alex Bennée]

From: Richard Henderson <richard.henderson@linaro.org>

This avoids a memcpy to the stack when compiled with clang.
Since we don't enable optimization, nor provide memcpy,
this results in an undefined symbol error at link time.
