Fix unintitialised TIC6X data
MALLOC_PERTURB_=1 results in the following fails due to uninitialised exindx data: FAIL: C6X unwinding directives 1 (little endian) FAIL: C6X unwinding directives 2 (big endian) FAIL: C6X unwinding directives 3 (segment change) FAIL: ld-tic6x/unwind-1 FAIL: ld-tic6x/unwind-2 FAIL: ld-tic6x/unwind-3 FAIL: ld-tic6x/unwind-4 FAIL: ld-tic6x/unwind-6 * config/tc-tic6x.c (s_tic6x_ehtype): Clear after frag_more. (tic6x_output_exidx_entry): Likewise. (md_apply_fix): Simplify 1 byte md_number_to_chars.
