The footprint is much smaller with uclibc.
look here for more deatils:

That problems are interesting and if you get problems with gcc you
should report them to the gcc-team to improve gcc.

That is right, but isn't possible to make a generic cross-toolchain for
ARM. The reason is we have a lot of different requremts on ARM.
e.g. compiler version gcc 2.95/3.2/3.3.x/3.4.x/4.0.x
( with or without c++/java/pascal/...)
binutils 2.14 / 2.15 / 2.16 / ...
libc glibc 2.2.x/ glibc 2.3.2 / glibc 2.3.5 / uclibc 0.27 /
uclibc 0.28 / dietlibc 0.xx
+ patches
You can select on ARM if you need a little end or big endian arch and
last but not least you have to decide if you need a softfloat support or
not.
What is your requirement ?

I never used Kegels scripts, so I am not sure, if it an option to remove
the condition. I think you will get more troubles. Try it it with
gcc-3.3 or gcc-3.4.
