Suppress Clang warning on adding an integer to a string, like:
tst-iconv-sticky-input-error.c:125:42: error: adding 'int' to a string does not append to the string [-Werror,-Wstring-plus-int]
125 | expected_output = "ABXY" + skip;
| ~~~~~~~^~~~~~
tst-iconv-sticky-input-error.c:125:42: note: use array indexing to silence this warning
125 | expected_output = "ABXY" + skip;
| ^
