I use a pretty simple workaround locally
 make -j 16 -k
 make -j 1

The first make will build all the object files, and then the 
second make links everything, in the right order...

The downside is that the first make will try to link things, and 
sometimes fail. But overall the compile goes more quickly.

BTW using -j 16 if you have 1 processor will of course slow things down, 
that is just the value I use when everything is coming from ccache. For 
a gentoo ebuild script you would probably want:
 make -k
 make -j1
So the user can set create a MAKE setting such as "MAKE=gmake -j2" or 
whatever works for them.
