ARM EABI: disable OABI support by default
OABI is rarely used in ARM EABI systems nowadays, so disable its support
by default. Add --enable-arm-oabi option to enable ARM OABI support.
* configure.ac: New option --enable-arm-oabi.
* syscall.c (get_scno) [ARM]: Check ENABLE_ARM_OABI macro defined by
configure instead of undocumented STRACE_KNOWS_ONLY_EABI macro.
