Any chance of a little help here please:

Grabbed latest git, compiled using the .config from Natanael's alpine 
git, I get near the end the following compile error:

Software versions:

gcc version 4.4.4 (Gentoo Hardened 4.4.4-r2 p1.2, pie-0.4.5)
GNU Make 3.81
build root running uclibc-0.9.31


I think this is a gcc specific issue right?  Or is it related to trying 
to build uclibc on uclibc?

Grateful for any pointers

Thanks
