I started off with a clean install of fedora 23 beta. I'm doing beta
first because it shouldn't be long (a few days?) until the release is
scheduled. https://fedoraproject.org/wiki/Releases/23/Schedule

After installing the default installation I finished answering the
install wizard after logging in and opened a terminal.

I ran: dnf -y distro-sync
to make sure all of the packages were up to date and rebooted.

After restarting, I logged in and opened a terminal again.
Git was installed by default, so I cloned down crosstool-ng.

None of the development tools were installed, so I installed the two
development groups:
sudo dnf -y groupinstall "Development Tools" "C Development Tools and Libraries"

I also installed: gperf, texinfo, patch, libstdc++-static,
glibc-static, expat-devel, expat-static and ncurses-devel

sudo dnf -y install gperf texinfo patch libstdc++-static glibc-static
expat-devel expat-static ncurses-devel

Changed to the directory where crosstool-ng was cloned. Ran
'./bootstrap', ran './configure --prefix="$HOME/.local"'. Then I ran
"make" then "make install".

I created a directory in my home directory called: "build/tc/" and
changed into it.
I made a directory called: arm-cortexa5-linux-uclibcgnueabihf
Then I changed into it and ran: ct-ng arm-cortexa5-linux-uclibcgnueabihf
Then I typed: ct-ng build

And the build finished successfully.

Did you make some other change to your
arm-cortexa5-linux-uclibcgnueabihf config before the build?
Do you have a build log?
