Bug #2612: Use POSIX shell in Makefile
http://redmine.ruby-lang.org/issues/show/2612

Author: Brian Egge
Status: Open, Priority: Normal
ruby -v: ruby 1.9.2dev (2010-01-19 trunk 26352) [i386-solaris2.10]

For some systems, including Solaris 10, /bin/sh is not a POSIX shell.  Certain features like the continue statement are missing from the /bin/sh shell on Solaris. Autoconf contains a macro which will set the appropriate POSIX shell for a system.

The following allows ruby to be built, and more specifically, cleaned without modification on Solaris 10.
