[RFA/commit] Work around Solaris bourne shell limitation when building the sim

Weird indeed. I thought it was related to the Solaris shell
misunderstanding the variable assignment as a command, or something
like that.  Your diff looks almost identical to mine, and yet mine
doesn't work, and I can't figure out why.

No matter, if you prefer this solution, here is a new complete diff.

sim/common/ChangeLog:

        * Make-common.in (hw-config.h): Work around bug in Solaris 2.8
        system bourne shell.

Tested on sparc-solaris with both /bin/sh and /bin/bash.

Thanks,
