3.0.1 PATCH: Substitute LIBICONV in gcc/Makefile.in

[Rainer Orth]

A fresh bootstrap of gcc 3.0.1 20010719 on alpha-dec-osf5.1 just failed
since jv-scan didn't link: 

stage1/xgcc -Bstage1/ -B/vol/gcc/alpha-dec-osf5.1/bin/  -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H  -o jv-scan java/parse-scan.o java/jv-scan.o version.o  obstack.o        -lmld -lexc ../libiberty/libiberty.a
/usr/bin/ld:
Unresolved:
iconv_open
iconv
iconv_close

This happens since java/Make-lang.in refers to $(LIBICONV), but the
AC_SUBST in aclocal.m4 has no effect at the moment, so the variable is
undefined, while Tru64 UNIX V5.1 needs -liconv for those functions.  The
patch below fixes this.  Ok for branch and mainline, provided the bootstrap
completes?
