commit 05ea2a051030a452bb1f4710dafeb1054cf38c17
Author: Tom Tromey <tom@tromey.com>
Date: Thu Dec 19 16:40:15 2019 -0700
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.
