The rx-linux target needs to behave differently than rx-elf.
Add an emulation for that.

rx-linux uses the common GCC ABI.
Setting RX ABI in ELF flags is wrong.
For rx-linux, change to generate GCC ABI objects.

2020-04-27 Yoshinori Sato <ysato@users.sourceforge.jp>
* config/tc-rx.c (elf_flags): Reset default value.
(md_parse_option): For rx-elf Initialize elf_flags with RX_ABI.
