[Bug libgcj/24154] New: Make requires too much memory building libjava

["ian at airs dot com" <gcc-bugzilla@gcc.gnu.org>]

GNU make requires too much memory building libjava.  On my system the virtual
memory size got up to 251M.  Since I only have 256M of RAM, make proceeded to
thrash.  I waited 45 minutes before killing it.

I am running i686-pc-linux-gnu, Fedora Core 4.

make hung at this point in the build:
