build: Support tcc, create tinycc-seed with tcc.

Browse source 
* configure: check for tcc.
* build-aux/cc32-mes.sh: Rename from cc-mes-gcc.sh.  Support
  tcc.  Update users.
* build-aux/build-cc32-mes.sh: Rename from build-mes-gcc.sh.  Update users.
* GNUmakefile (mes-tcc): New target.
* .gitignore: Ignore mes-tcc arch output.
* lib/crt1.c (_start): Add "rm" constraint so satisfy tcc.
* lib/linux-gcc.c (_sys_call, _sys_call1 _sys_call2 _sys_call3): Likewise.
