[haiku-development] Building GCC 2.95 in a x86_64 machine.

I tried to compile Haiku with the legacy GCC under Linux so I could run R5 applications on it. The cross-compiler build failed:
( cd /home/bga/haiku/src/haiku/trunk/generated/cross-tools/lib ; ranlib ./libiberty.an ) mv -f /home/bga/haiku/src/haiku/trunk/generated/cross-tools/lib/./libiberty.an /home/bga/haiku/src/haiku/trunk/generated/cross-tools/lib/./libiberty.a 
if test -n ""; then \
          case "" in \
            /*)    thd=;; \

          esac; \
