3.4.0 fails to bootstrap on sh4-unknown-linux-gnu because of
the hang-up when compiling libstdc++-v3/testsuite/abi_check.cc.
It seems that the i686-linux x sh4-unknown-linux-gnu behaves
same as the native compiler and with -fno-unit-at-a-time both
native and cross cc1plus compiles abi_check.cc normally.
FYI, when it looks halting, cross cc1plus takes almost cpu time:

and gdb attatched to it says

Do you know if the bug is present also on the 3.3 branch or on mainline?

The mainline (20040425 x86-linux cross to sh4-linux) also hangs on .i file
got from 3.4.0 abi_check.cc. Unfortunately, same .i file can't be compiled
on 3.3-branch for another reasons like new __attribute__ expression and I
don't have any appropriate testcase for this PR against 3.3-branch ATM.

Can you attacch the precompiled file to this report for completeness? Maybe
someone will have time to reduce this, making it possible to test it on 3.3.
