[Bug other/43445] New: Toplevel Makefile needs to export ABI variants of LD_LIBRARY_PATH

["ro at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

During a libjava build on i386-pc-solaris2.11, I noticed the following error:

ld.so.1: gcj-dbtool: fatal:
/vol/gcc/obj/gcc-4.5.0-20100208/11-gcc-gld/./gcc/libgcc_s.so.1: wrong ELF
class: ELFCLASS32
/bin/ksh: 29209 Killed

This happens when trying to execute the 64-bit gcj-dbtool.  gcj-dbtool itself
is a libtool wrapper script, which allows it to find the dependend libtool
libraries, but for libgcc_s.so.1, it relies on HOST_EXPORTS in the toplevel
Makefile to export LD_LIBRARY_PATH via RPATH_ENVVAR, it refers to
TARGET_LIB_PATH and HOST_LIB_PATH, but none of them is multilib aware.

The toplevel Makefile probably needs to set all of LD_LIBRARY_PATH{, _32, _64}
and their IRIX and Darwin equivalents.  See
gcc/testsuite/lib/target-libpath.exp
for the full list.
