Move many configure checks to common.m4

This moves many needed configure checks from gdb and gdbserver into
common.m4.  This helps gdbsupport, nat, and target be self-contained.

The result is a bit spaghetti-ish, because gdbsupport uses another m4
file from gdb/.  The resulting code is somewhat non-obvious.  However,
these problems already exist, so it's not really that much worse than
what is already done.
