this broke bootstrap on i386-pc-solaris2.12, sparc-sun-solaris2.12, and
i686-pc-linux-gnu (probably every 32-bit host), as confirmed by an
i386-pc-solaris2.10 reghunt.
E.g. in the Linux/i686 bootstrap, compiling tree-ssa-math-opts.o fails
with
virtual memory exhausted: Cannot allocate memory
In the Solaris cases, various libstdc++ source files fail to compile in
the same way.
