Default e_machine to EM_IAMCU for i?86-*-elfiamcu
This patch sets the default ELF output format of assembler and linker to EM_IAMCU when binutils is configured to i?86-*-elfiamcu target. gas/ * configure.tgt (arch): Set to iamcu for i386-*-elfiamcu target. * config/tc-i386.c (i386_mach): Support iamcu. (i386_target_format): Likewise. ld/ * configure.tgt: Support i[3-7]86-*-elfiamcu target. ld/testsuite/ * ld-i386/i386.exp (iamcu_tests): Run iamcu-4. * ld-i386/iamcu-4.d: New file.
