[GUB] libc.so.6: undefined reference to address@hidden'

[Federico Bruni]

My latest attempt to build GUB (on LilyDev Debian 9, gcc version 6.3.0) 
failed when building guile for linux-x86.

Here's the tail:

libtool: link: (cd ".libs" && rm -f "libguile.so.17" && ln -s 
"libguile.so.17.3.1" "libguile.so.17")
libtool: link: (cd ".libs" && rm -f "libguile.so" && ln -s 
"libguile.so.17.3.1" "libguile.so")
libtool: link: ( cd ".libs" && rm -f "libguile.la" && ln -s 
"../libguile.la" "libguile.la" )
/bin/bash ../libtool --tag=CC --mode=link i686-linux-gcc -g -O2 -Wall

Attached the full log: target/linux-x86/log/guile.log

What can I try to work around this?

Thanks
