[RFC 03/17] Move event-loop configury to common.m4

- Subject: [RFC 03/17] Move event-loop configury to common.m4
- References: <20190224165153.5062-1-tom@tromey.com>
gdb_select.h and the event loop require some configure checks, so this
moves the needed checks to common.m4 and updates the configure
scripts.
gdb/ChangeLog
2019-02-24 Tom Tromey <tom@tromey.com>
* common/common.m4 (GDB_AC_COMMON): Check for poll.h, sys/poll.h,
sys/select.h, and poll.
* configure: Rebuild.
* configure.ac: Remove checks that are now in GDB_AC_COMMON.
gdb/gdbserver/ChangeLog
2019-02-24 Tom Tromey <tom@tromey.com>
* configure: Rebuild.
* config.in: Rebuild.
