Since the introduction of the configure check for the --no-merge-exidx-entries
linker option, all libjava tests fail on IRIX 6.5:

output is:
(null): WARNING 1  : Unknown option: -no-merge-exidx-entries (ignored).


FAIL: linking PR9577

The problem is that the SGI ld warns about unknown options as above, but still
exists with status 0.  None of the options to suppress errors/warnings has an
effect on this, neither -LD_MSG:error=1 nor -LD_MSG:off=1 nor -woff 1.

I've found no good way to handle this generically, since the AC_LINK_IFELSE
macro only logs stderr of the link command to conftest,err and the warning
goes to stdout.  I could of course simply set libgcj_cv_exidx=no for
mips-sgi-irix6.5, but perhaps there's a cleaner solution I'm just not seeing?
