hardened / non-hardened stage3?

binutils version (maybe gcc too) ?

these are relocations related to PIE/PIC ( hardened gcc used? )

bad for you, your build env seems to be broken

uclibc in USE is obsoleted (this was replaced by elibc_uclibc, but does 
not have to be added to USE - "autodetected" - )

what kernel headers are installed and if you switched from headers 2.4 to 
2.6, have you also rebuilt at least uclibc?

X works, you have a problem generally with your build environment.
a. IIRC the stages are built w/ kernel-headers-2.4, if you want to use 
2.6, it would be better to start from stage1 and rebuild everything
b. haven't tested current hardened stage3, but if I would want hardened 
uClibc freshly installed, I would also start from a stage1.
To check why I say b. run (consider adding all the dirs from your PATH to 
the command below)
file /bin/* /usr/bin/* /sbin/* /usr/sbin/* | grep ELF | grep -v 'shared 
object'
The listed files (executables) should all be static binaries, if they are 
not, the packages providing those files were not built hardened.

kdrive is obsoleted (at least IMHO), try maybe the modular-X (emerge 
xorg-server), package masked.
