We have traditionally handled this using two helper binaries that does the work of objcopy, but this has been error prone and is not a really nice solution. And by now, a fixed version of objcopy has been long time available in Solaris.

I noticed that I left some debug code in toolchain.m4, and also didn't 
use variables like $SED for the commands.

I might also add that the compex sed expression is copied from the 
corresponding check in the hotspot makefiles.

Updated webrev:  (only changed in toolchain.m4)
