Hello!
With gcc-11, the Go compiler is now used during the bootstrap process
which causes the build of gcc-11 and gcc-snapshot to fail on ia64 as
Go doesn't properly work there at the moment [1]:

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
Could you therefore disable Go on ia64 for the time being in both gcc-11 and -snapshot?
Thanks,
Adrian
