Fix perror in gdb.opt/fortran-string.exp

When running the test-case gdb.opt/fortran-string.exp from
gdb-archer-vla-tests.patch, we run into:
ERROR: couldn't run to breakpoint MAIN__
The test case attempts to set a breakpoint on a line containing an "s = s"
assignment and when that doesn't work, it error out with above error message.

The test-case executable is optimized, and the "s = s" assignment is optimized
away, so there's not really an error, it's just that the test-case is
unsupported due to the optimizations done by the compiler.

Fix this by replacing the ERROR with UNSUPPORTED.

	* gdb.opt/fortran-string.exp: Replace error with unsupported.
