[uClibc] buildroot gcc-4 proposed changes

[Peter S. Mazinger]

Hello!

gcc-4.1.0 support was added to buildroot. Comparing my gcc-4.0.0 
patches with those added to buildroot, I got the attached diffs. I do not 
know if they apply to the not-released 4.1.0. The generic one adds alpha
support (and shortens i386 part).
The cxx patch disables reference to a file that was removed from gcc-4.0.0
Check if this is the case for gcc-4.1.0 too.

If someone would review the math patches added to bugs.uclibc.org and 
apply them to the uclibc tree (implements all SuSv3 math requirements), 
then the hack to disable math functions (float/double) from the 
gcc/libstdc++ patch could go away.

Thanks, Peter
