[RFA] Patch to gas-test.scm

[Ben Elliston <bje at redhat dot com>]

Here is a convenient enhancement that makes it possible to omit the
path to the gas build tree when cgen has been configured as part of a
larger tree.  Okay to commit?

2000-10-31  Ben Elliston  <bje@redhat.com>

	* gas-test.scm (cgen-build.sh): Allow the generated script to run
	with no command line arguments if the gas build directory can be
	determined.
