Problem building the gdb-14-branch probably due to GMP

[Nat!]

When I build a somewhat slimmed down gdb, I get the following error:

```
   CXX    init.o
   CXXLD  gdb
./libtool: line 5209: cd: no/lib: No such file or directory
libtool: link: cannot determine absolute directory name of `no/lib'
make[2]: *** [Makefile:2186: gdb] Fehler 1
make[2]: Verzeichnis „/home/src/srcL/gdb-14-branch/gdb“ wird verlassen
```

 From the Makefile I deduced that this has something to do with GMP, 
which I don't need, so I configured that out. But it made no difference.

I am on:

```
commit 2b5f0fe3230f707ab736d759af4bf436d2c43837 (HEAD -> master,

I want to build a slimmed down gdb, therefore I leave out a few 
configuration options.

```
./configure \
    --disable-binutils \
    --disable-ld \
    --disable-gold \
    --disable-gas \
    --disable-sim \
    --disable-gprof \
    --disable-gprofng \
    --disable-libmcheck \
    --disable-gprofng \
    --enable-64-bit-bfd \
    --with-separate-debug-dir="/usr/lib/debug" \
    --with-system-gdbinit="/etc/gdb/gdbinit" \
    --with-curses \
    --without-gmp \
    --without-mpfr \
    --without-expat \
    --without-guile \
    --without-lmza \
    --without-intel-pt \
    --without-python \
    --without-tcl \
    --without-tk \
    --with-tui \
    --without-libunwind-ia64 \
    --without-x \
    --without-babeltrace
```


As an experiement I reduced this to

```
./configure
    --disable-binutils    \
    --disable-ld  \
    --disable-gold \
    --disable-gas \
    --disable-sim \
    --disable-gprof \
    --disable-libmcheck \
    --disable-gprofng \
    --without-gmp
```

and build this (doing a git clean -d -f beforehand. It doesn't work 
either, but on a rerun I get this funny error:

```
configure: loading cache ./config.cache
configure: error: `GMPLIBS' has changed since the previous run:
configure:   former value:  `-Lno/lib -Lno/lib -lmpfr -lgmp'
configure:   current value: `-Lno/lib -lmpfr -lgmp'
configure: error: `GMPINC' has changed since the previous run:
configure:   former value:  `-Ino/include -Ino/include '
configure:   current value: `-Ino/include '
configure: error: in `/home/src/srcL/gdb-14-branch/gdb':
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm ./config.cache' and 
start over
```

Something seems out of whack with respect to GMP in the build process.
