Error in linking ?

[GeOdys]

Hello to all.

In a Void Linux installation I followed the steps:

1. git clone git://gcc.gnu.org/git/gcc.git gcc-git
2. cd gcc-git
3. mkdir build
4. cd build
5. sudo vpm install -y gmp gmp-devel gmpxx gmpxx-devel mpfr mpfr-devel 
mpc libmpc libmpc-devel libmpcdec libmpcdec-devel flex dejagnu
6. ../configure --enable-languages=m2 --disable-multilib --prefix=$HOME/opt
7. make -j 30
8. make install

then the last one resulted in:

ANY ideas?

Thank you in advance!
