thanks for looking this up.  However, further digging revealed that the
issue is slightly different for me.  When I run a single testcase
(alias.exp), gdb.log shows

(gdb) ^M^[[K(gdb) alias -a set2=set^M
(gdb) ^M^[[K(gdb) FAIL: gdb.base/alias.exp: alias -a set2=set (timeout)

i.e. I get clr_eol/el (clear to end of line) after the prompt which
confuses the test framework.  I haven't yet found what causes this.
However, I managed to hack around the issue for testing purposes by
configuring with --disable-tui: this way at least a vast majority of the
tests PASS.

The same issue still happens when I use a locally built libncurses 5.7
instead of the native libcurses.
