* config/tc-i386.c (tc_gen_reloc): Accept all relocs; remove
#ifndef OBJ_ELF lines. From Eric Valette <valette@crf.canon.fr>. (tc_gen_reloc): If out of memory call as_fatal rather than assert. If no howto found, call as_bad_where rather than as_fatal. Change the error message slightly. Set howto to a non-NULL value in order to keep going.
