Is there something sytematically wrong with libiberty? Building the latest snapshot (gcc-core-20030512) for avr also breaks on libiberty. make install has makefile rule problems:
gcc -c -g -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long -DHAVE_CONFIG_H -DGENERATOR_FILE -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/config -I../../gcc/../include ../../gcc/gengenrtl.c -o gengenrtl.o make[1]: *** No rule to make target `../libiberty/libiberty.a', needed by `gengenrtl'. Stop.
I just built several GCCs from the same snapshot and in every case the build-libiberty was produced ok. My build system was RedHat 7.1 with 7.2 and 7.3 stuff used as the update material... So you should double-check the '$build/libiberty' subdir, look at the 'config.log' for any possible failure, do a 'make distclean' there, try to reconfigure only there and then try to rebuild. Without the 'config.log' it is hard to tell what went wrong....
In this case, the configure step warned:
checking host system type... i686-pc-linux-gnu checking target system type... avr-unknown-none checking build system type... i686-pc-linux-gnu *** This configuration is not supported in the following subdirectories: target-libiberty (Any other directories should still work fine.)
