correct.

in fact we do not even link against ncurses, as gdb can be built against
the much smaller termcap library.
(however ncurses will be picked up automatically if it was installed
before building gdb, no problems there either.)

also for the record, the problem you encountered with -fPIC was due to a
.so built unconditionally during gdbserver compilation, and if you have
-static in your LDFLAGS, the buildsystem will try to create the .so with
both -shared and -static, instead of stripping the -static off for
that step.
--disable-inprocess-agent can be used to get gdbserver without building
that dso, which seems rather useless anyway.
