Thanks, I solved this problem. But now I get:

checking for sched.h... yes
checking for thread model used by GCC... posix
checking whether the target supports thread-local storage... yes
checking for exception model to use... configure: error: unable to
detect exception model
make[1]: *** [configure-target-libobjc] Error 1
make[1]: Leaving directory `/home/german/Instalados/GCC/objdir'
make: *** [all] Error 2

config.log say:

configure:11454: result: yes
configure:11462: checking for exception model to use

I searched on Internet, but can't find a solution for this.
