Currently, the bundled CT-NG config file has no C library configured.
It is quite complex to add and/or munge options in this case.
Now, with one config file per libc familly, it becomes easier.

1.11.3 is the latest stable version, and it has a few improvements
we'll find usefull. For example, it hasa a boolean option for
disabling the {,e}glibc fortified build (instead of requiring us
to shoehorn it in extra cflags.

Jacmet on IRC reported some build failures for different targets.
They were of two kinds:
- missing/unknown stack unwinding support
- missing *_chk functions
The first is about configure not being able to automagically determine
if stack unwinding support is available for the target. The second is
about fortified build forgetting to build the fortified functions.
This applies to both glibc and eglibc.
After some discussions on IRC with Jacmet, it appears that we can
safely assume both of the following:
- virtually all targets of buildroot will have stack unwinding support
- we do not care about fortified builds (so far)
So, update the bundled crosstool-NG .config file to saner defaults:
- force unwind support
- disable fortified builds

Well, I know this is a bit late, and -rc1 is out.
It's been pretty busy here, and I do apologise for the delay in handling
this issue...

- force unwind support
- disable fortified builds
