gas: fix building tc-bpf.c on s390x
char is unsigned on s390x, so there are a lot of warnings like:
gas/config/tc-bpf.c: In function 'get_token':
gas/config/tc-bpf.c:900:14: error: comparison is always false due to limited range of data type [-Werror=type-limits]
900 | if (ch == EOF || len > MAX_TOKEN_SZ)
| ^~
Change its type to int, like in the other similar code.
There is also:
gas/config/tc-bpf.c:735:30: error: 'bpf_endianness' may be used uninitialized in this function [-Werror=maybe-uninitialized]
735 | dst, be ? size[endianness - BPF_BE16] : size[endianness - BPF_LE16]);
| ~~~~~~~~~~~^~~~~~~~~~
-Wmaybe-uninitialized doesn't seem to understand the FSM; just
initialize bpf_endianness to silence it. Add an assertion to
build_bpf_endianness() in order to catch potential bugs.
