Patch: Makefile.am -vs- `gcj -C' failure

[Tom Tromey <tromey at redhat dot com>]

Bryce pointed out that `make' in libgcj will keep going even if a
bytecode compilation fails.  This patch fixes the problem.  I'm
checking this in on the trunk.

The problem was that the `while' was being run in a subshell, so the
test at the end always saw `$fail' as `no'.  Putting the while and the
test into a subshell fixes this.

Tested on my x86 RH Linux 6.2 box.
