[JAVA] /bin/sh portability issues in scripts/check_jni_methods.sh

[Roger Sayle <roger at eyesopen dot com>]

This patch, or more likely request for help, is the fourth and final
in the series to enable mainline GCC to be bootstrapped with the native
/bin/sh on Solaris/x86.  The current build failures are a regression
from gcc 3.4.  These four patches appear to address all of the build
system related issues with the default build.

Now for the admission.  This final patch, to scripts/check_jni_methods.sh
is more of a workaround (hack?) than a solution to the portability issues.
The problem is that this shell script contains the command "set -C" which
isn't supported by Solaris' sh.  Commenting it out, stops the script from
terminating with a hard error, and enables libjava to reach the
application linking steps at the end of the build (which suffer from
boehmgc issues that I may not have resolved correctly).

However, I've no idea what the correct way to fix this problem is.  I
did discover that this issue is related to PR other/2141, which was a
similar use of "set -C" in gccbug.  The solution there was to reorganize
the script to avoid the need for this functionality.

If any shell scripting gurus could take a look and see what the
correct fix for this problem is, it'd be much appreciated.

Many thanks in advance,

	* scripts/check_jni_methods.sh: Don't use the "set -C" command
	which isn't available in all shells.
