Since this commit:
commit 64aaad6349d2b2c45063a5383f877ce9a3a0c354
Date: Fri Sep 25 14:50:56 2020 +0100
gdb: use get_standard_config_dir when looking for .gdbinit
GDB has been checking for ${XDG_CONFIG_HOME}/gdb/gdbinit on startup.
Most tests pass -nx to GDB to block loading of gdbinit files, but
there are a few tests (e.g. gdb.base/gdbinit-history.exp) that don't
use -nx and instead setup a fake HOME directory containing a gdbinit
file.
However, since the above commit, if XDG_CONFIG_HOME is set then once
-nx is no longer being passed GDB will load any gdbinit file it finds
in that directory, which could cause the test to fail.
As a concrete example:
$ mkdir -p fake_xdg_config_home/gdb/
$ cat <<EOF >fake_xdg_config_home/gdb/gdbinit
echo goodbye\n
quit
EOF
$ export XDG_CONFIG_HOME=$PWD/fake_xdg_config_home
$ make check-gdb TESTS="gdb.base/gdbinit-history.exp"
Should result in the test failing.
The solution I propose is to unset XDG_CONFIG_HOME in
default_gdb_init, we already unset a bunch of environment variables in
this proc.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (default_gdb_init): Unset XDG_CONFIG_HOME.

Seems reasonable to me.
