Re: [gentoo-hardened] glibc not using PIE

[Kerin Millar]

Try without distcc, with a conservative MAKEOPTS setting and always  
ensure that the toolchain is built in this order: binutils, gcc,  
glibc. Failing that, you could bootstrap (be wary of /etc clobbering  
by baselayout) or roll the affected package again in a "clean" chroot  
before exporting it to the host.

Apologies for the top post - my mobile device makes it unfeasible to  
post in the usual manner.

Cheers,
