I see exactly the same error trying to build libgo on sparc-sun-solaris2.11.

sparc-sun-solaris2.11 bootstrap with Go included succeeded now (with a
couple of libgo patches already posted), make check still running, but
gcc/testsuite/go testresults look good:

        === go Summary ===

# of expected passes        5746
# of unexpected failures    16
# of expected failures        48
# of untested testcases        4

Thanks.
