gcc-4.2.4 fails to bootstrap on Solaris10/x86 as follows:

env CONFIG_SHELL=/usr/bin/bash /home/mikpe/gcc-4.2.4/configure
--prefix=/opt/local/gcc-4.2.4 --with-gnu-as
--with-as=/opt/local/binutils-2.18/bin/as --without-gnu-ld
--with-ld=/usr/ccs/bin/ld --enable-threads=posix --disable-shared
--enable-multilib --enable-nls --with-included-gettext
--with-libiconv-prefix=/opt/csw --enable-java-awt=xlib --with-system-zlib
--enable-languages=c,c++ --with-mpfr=/opt/csw
make bootstrap
checking sys/sem.h presence... yes
checking for sys/sem.h... yes
checking for sin in -lm... configure: error: Link tests are not allowed after
make[1]: *** [configure-target-libstdc++-v3] Error 1
make[1]: Leaving directory `/home/mikpe/objdir-4.2.4-static'
make: *** [bootstrap] Error 2

I have previously built gcc-4.1.2 and gcc-4.2.3 successfully on this
system, so this failure is an obvious regression.

Testing older 4.2 snapshots showed that 4.2-20080206 was the last
snapshot that built ok, and 4.2-20080213 is the first one that fails.

Inspecting the diff between 20080206 and 20080213 and testing parts
of it separately has identified H.J. Lu's fix for PR31868 as the
culprit. Specifically, after that change crtstuff.c is compiled with
-fno-asynchronous-unwind-tables which it wasn't before the change.
20080213 minus the -fno-asynchronous-unwind-tables change builds fine.

I haven't yet checked if gcc-4.3 is similarly affected because I needed
to resolve a generic 4.3 problem first (PR36339).
