This won't be necessary: ${libgcj} isn't in the toplevel configure.in's
noconfigdirs for i?86-*-solaris2*, so it will be enabled by default.

Seems dangerous, given that you need the kernel config trickery to get a
reasonable command line length limit.

They are listed in

Here's the overview for the spec changes:
*-*-solaris2* and mips-sgi-irix6* need REFERENCESPEC (i.e. -fcheck-references)
i?86-*-solaris2* needs the default DIVIDESPEC (i.e. -fuse-divide-subroutine)
Looking into this, I noticed a problem: right now, we have
libjava/configure.host. Comparing this to the libstdc++-v3 situation, this
seems wrong: this should be configure.target and there should be separate
switches on target_cpu, target_os and the full target triple. Otherwise,
handling the common Solaris 2 REFERENCESPEC becomes messy. If there's
agreement that this is the right way to handle this, I can provide a patch.

Indeed: libjava/testsuite/lib/libjava.exp hardcodes -B$objdir in several
places to have gcj find the uninstalled libgcj.spec. This doesn't take
multilibs into account. I won't be able to work on a patch now, since I'll
be away soon until wednesday.
