[uClibc] libgcc_s.so.1

[Wayne Ingram]

Hi John,

I've just compiled xorg against uclibc sucessfully for the first time
and I have noticed the same dependancy on libgcc_s.so.1 At first I
thought that I had missed the lib when packaging uclibc, so after
looking for it on my devel system, I noticed that it is quite large,
around 35M and I'm trying to make a small cutdown system!

Non of my other software I have complied requires this library, so I'm
hoping i can get around it.

Wayne.
